Q4. Word Problems:

Question 1. Vinod had Rs 100/- and went to a shop. He bought a packet of chewing gums for Rs 12/- and an ice cream pack for Rs 52/-. How much money he is left with -
(a) Rs 82/-
(b) Rs 36/-
(c) Rs 48/-
(d) Rs 64/-
Answer: (b) Rs 36/-
Total spent = \(12 + 52 = \text{Rs. } 64\)
Money left = \(100 - 64 = \text{Rs. } 36\)
In simple words: Add the cost of the items bought and subtract the total from the initial amount of Rs. 100.

Exam Tip: Two-step word problems require calculating total expenses first, then finding the remaining balance.

Question 2. There are 8 pieces of a chocolate bar. Mother gave 7 pieces to Raj and he shared 2 pieces with Ravi. What part of chocolate bar was left with Raj?
(a) 7/8
(b) 5/7
(c) 5/8
(d) 2/5
Answer: (c) 5/8
Raj received 7 pieces out of 8.
He gave away 2 pieces, so pieces remaining with Raj = \(7 - 2 = 5\).
Fraction left with Raj = \(\frac{5}{8}\)
In simple words: Raj kept 5 out of the total 8 pieces.

Exam Tip: Fractions represent part over the total number of equal parts.

Question 3. After distributing 5 chocolates each among 8 children 3 were left in the bag. How many chocolates were there in the bag -
(a) 15
(b) 40
(c) 43
(d) 45
Answer: (c) 43
Chocolates distributed = \(8 \times 5 = 40\)
Chocolates left in bag = 3
Total chocolates = \(40 + 3 = 43\)
In simple words: Multiply children by chocolates per child, then add the leftover chocolates.

Exam Tip: Total = (Number of groups \(\times\pi\) items per group) + remainder.

Question 4. Out of 2970 students in a school, 1060 are in primary department, 930 in middle department and the remainders are in the senior department. The number of students in senior department are -
(a) 1990
(b) 980
(c) 1570
(d) 1750
Answer: (b) 980
Students in primary and middle = \(1060 + 930 = 1990\)
Students in senior department = \(2970 - 1990 = 980\)
In simple words: Add primary and middle students, then subtract from the total student population.

Exam Tip: Subtract combined sub-totals from the overall total to find the remaining category.

Question 5. There were altogether 20 sweets. You took 12 for yourself and gave 8 to your friend. Your friend gets ____________ fraction of sweets -
(a) 8/20
(b) 20/8
(c) 12/20
(d) 8/12
Answer: (a) 8/20
In simple words: Your friend received 8 sweets out of a total of 20, which is expressed as the fraction \(\frac{8}{20}\).

Exam Tip: The denominator represents the total number of items, and the numerator represents the part given or taken.

Question 6. A wooden plank is 8 m 50 cm long. A length of 2 m 15 cm is cut from it. How much of the plank will remain -
(a) 2 m 35 cm
(b) 6 m 45 cm
(c) 6 m 35 cm
(d) None of these
Answer: (c) 6 m 35 cm
Subtract centimeters: \(50\text{ cm} - 15\text{ cm} = 35\text{ cm}\)
Subtract meters: \(8\text{ m} - 2\text{ m} = 6\text{ m}\)
Remaining length = 6 m 35 cm
In simple words: Subtract the centimeters and meters separately.

Exam Tip: Double-check whether borrowing from the meter unit is required for centimeters subtraction.

Question 7. The number of children who opted for cricket is double the number of those who opted for football. If the number of students who opted for football is 3 less than 3 times 13 then the number of the students who opted for cricket is -
(a) 36
(b) 39
(c) 69
(d) 72
Answer: (a) 36 (Wait, let's calculate carefully: Football students = \((3 \times 13) - 3 = 39 - 3 = 36\). Cricket students = double of football = \(36 \times 2 = 72\). Let's check options: (a) 36, (b) 39, (c) 69, (d) 72. Option (d) is 72.)
Correct Answer: (d) 72
In simple words: Calculate football students first (\(39 - 3 = 36\)), then double that number to find cricket students (\(36 \times 2 = 72\)).

Exam Tip: Break multi-step word problems into sequential chronological calculations.

Question 8. The party lasted for 6 hrs 30 mins but I came back one and a half hour earlier. How much time did I spend in the party -
(a) 5 hrs
(b) 6 hrs
(c) 5 hrs 30 mins
(d) 1 hr 30 mins
Answer: (c) 5 hrs 30 mins
Duration of party = 6 hrs 30 mins
Time left early = 1 hr 30 mins (one and a half hour)
Time spent = \(6\text{ hrs } 30\text{ mins} - 1\text{ hr } 30\text{ mins} = 5\text{ hrs}\)? Wait, \(30 - 30 = 0\) mins, and \(6 - 1 = 5\) hrs, so 5 hours! Let's check option (a) 5 hrs.
Let's re-verify: \(6\text{ hrs } 30\text{ mins} - 1\text{ hr } 30\text{ mins} = 5\text{ hrs} 00\text{ mins}\). Option (a) 5 hrs.
In simple words: Subtract 1 hour 30 minutes from 6 hours 30 minutes to get exactly 5 hours.

Exam Tip: Subtract hours from hours and minutes from minutes.

Question 9. Rajiv's home is about 8 km 750 m from the school; Chetan's home is about 2 km 500 m less far than the distance of Rajiv's home from the school. The distance between Chetan's home and the school is -
(a) 6 km 250 m
(b) 10 km 750 m
(c) 11 km 250 m
(d) 6 km 750 m
Answer: (a) 6 km 250 m
\(8\text{ km } 750\text{ m} - 2\text{ km } 500\text{ m} = 6\text{ km } 250\text{ m}\)
In simple words: Subtract Chetan's shorter distance from Rajiv's distance.

Exam Tip: "Less far" indicates subtraction.

Question 10. I read \(\frac{4}{9}\) of a story book yesterday. Today I read \(\frac{2}{9}\) of it. How much part I read in 2 days
(a) \(\frac{6}{18}\)
(b) \(\frac{6}{9}\)
(c) \(\frac{2}{9}\)
(d) \(\frac{8}{9}\)
Answer: (b) \(\frac{6}{9}\)
Total part read = \(\frac{4}{9} + \frac{2}{9} = \frac{4 + 2}{9} = \frac{6}{9}\)
In simple words: Add the numerators while keeping the common denominator 9.

Exam Tip: When adding like fractions, add only the numerators and keep the denominator unchanged.
