Ques.3 Find:-
हल करो |
1. \(100 \div 20 - 5 \times 2 + 60 \div 2\)
2. \(15 \times 5 - 12 \times 6 + 4\)
3. \(19 \times 5 - 18 \times 12 \div 5\)
4. \(48 + 72 \div 9 \times 3 - 5 \times 7 + 4\)
Answer:
1. Using BODMAS rule:
\(100 \div 20 = 5\)
\(5 \times 2 = 10\)
\(60 \div 2 = 30\)
\(= 5 - 10 + 30\)
\(= 35 - 10 = 25\) (Note: Standard calculation gives 25, while answer key notes 0 based on strict sequential processing; follow standard BODMAS yielding 25).
2. \(15 \times 5 - 12 \times 6 + 4\)
\(= 75 - 72 + 4\)
\(= 3 + 4 = 7\)
3. \(19 \times 5 - 18 \times 12 \div 5\)
\(= 95 - 216 \div 5\)
\(= 95 - 43.2 = 51.8\)
4. \(48 + 72 \div 9 \times 3 - 5 \times 7 + 4\)
\(= 48 + 8 \times 3 - 35 + 4\)
\(= 48 + 24 - 35 + 4\)
\(= 72 - 35 + 4 = 37 + 4 = 41\)
In simple words: Solve mathematical expressions by following the BODMAS order of operations (Division, Multiplication, Addition, Subtraction).

Exam Tip: Always perform division and multiplication before addition and subtraction.

Ques.4 Divide the greatest no. of four digits by 95.
४ अंको की सबसे बड़ी संख्या को ९५ से भाग करो |

Answer:
Distance covered in 15 L of petrol = 225 km
Distance covered in 1 L of petrol = \(225 \div 15 = 15\text{ km}\)
Distance covered in 10 L of petrol = \(15 \times 10 = 150\text{ km}\)
In simple words: Calculate how far the car goes on 1 liter (225 divided by 15), then multiply by 10.

Ques.7 The rent of a house for a year is Rs. 2400 find the rent for 3 months?

Answer:
Rent for 1 year (12 months) = Rs. 2400
Rent for 1 month = \(2400 \div 12 = \text{Rs. } 200\)
Rent for 3 months = \(200 \times 3 = \text{Rs. } 600\)
In simple words: Divide the yearly rent by 12 to find the monthly rent, then multiply by 3.

Exam Tip: Remember that 1 year equals 12 months.

Cost of biscuit = Rs. 4.75
Total money spent = \(5.75 + 4.50 + 4.75 = \text{Rs. } 15.00\)
In simple words: Add the prices of the bread, butter, and biscuits to find the total money spent.

Exam Tip: Align decimal points properly when adding decimal money amounts.

Ques.10 Write the time that.
समय बताओ |
(i) 10 min. earlier then 9:30.
9:30 से १० मिनट पहले |

4:45 से १० मिनट बाद |
(iii) \(\frac{1}{2}\text{ h.}\) earlier than 10:45.
10:45 से आधा घंटा पहले |
Answer:
(i) \(9:30 - 10\text{ minutes} = 9:20\)
(ii) \(4:45 + 10\text{ minutes} = 4:55\)
(iii) \(10:45 - 30\text{ minutes} = 10:15\)
In simple words: Subtract minutes for earlier times and add minutes for later times.

Exam Tip: Half an hour is equal to 30 minutes.

Ques.11 A ration dealer distributed 945 liter kerosene equally to 27 persons. How much oil did each person get?
एक राशन डीलर ९४५ लीटर मिट्टी का तेल २७ लोगों को बराबर बाँटता है| प्रत्येक आदमी को कितना तेल मिलेगा ?
Answer:
Total kerosene = 945 liters
Number of persons = 27
Kerosene each person gets = \(945 \div 27 = 35\text{ liters}\)
In simple words: Divide the total quantity of oil by the number of people.

Exam Tip: Check your division by multiplying 35 by 27 to get 945.

Answer:
(i) \(2315\text{ hours} = 11:15\text{ pm}\)
(ii) \(1709\text{ hours} = 5:09\text{ pm}\)
In simple words: Convert 24-hour timings greater than 1200 into 12-hour p.m. format by subtracting 1200 hours.

Exam Tip: Subtract 12 from the hour part when the time is from 1300 to 2359.

Ques.14 A gas cylinder contains \(14 \frac{3}{5}\text{ kg}\) of gas \(9 \frac{3}{5}\) is used. How much of Gas is left in the cylinder?
एक गैस सिलिंडर में १४ ३/५ किलोग्राम गैस है यदि उसमे से ९ ३/५ किलोग्राम इस्तेमाल की गई तो सिलिंडर में कितनी गैस बाकी बची ?
Answer:
Initial gas in cylinder = \(14 \frac{3}{5}\text{ kg}\)
Gas used = \(9 \frac{3}{5}\text{ kg}\)
Gas left = \(14 \frac{3}{5} - 9 \frac{3}{5}\)
\(= (14 - 9) + \left(\frac{3}{5} - \frac{3}{5}\right)\)
\(= 5 + 0 = 5 \frac{3}{5}\text{ kg}\)
In simple words: Subtract the used quantity from the initial quantity by subtracting whole numbers and fractions separately.

Exam Tip: When denominators are identical, subtract only the numerators.

Ques.15 The population of a town is 96,954. How much is less than one lakh?
एक शहर की कुल जनसंख्या ९६,९५४ है तो यह एक लाख से कितनी कम है ?

Population of town = 96,954
Difference = \(1,00,000 - 96,954 = 3,046\)
In simple words: Subtract the town's population from 1,00,000 to find the difference.
