Question 1. Write the roman numbers from 1 to 100
Answer:
1 = I, 2 = II, 3 = III, 4 = IV, 5 = V, 6 = VI, 7 = VII, 8 = VIII, 9 = IX, 10 = X
11 = XI, 12 = XII, 13 = XIII, 14 = XIV, 15 = XV, 16 = XVI, 17 = XVII, 18 = XVIII, 19 = XIX, 20 = XX
21 = XXI, 22 = XXII, 23 = XXIII, 24 = XXIV, 25 = XXV, 26 = XXVI, 27 = XXVII, 28 = XXVIII, 29 = XXIX, 30 = XXX
31 = XXXI, 32 = XXXII, 33 = XXXIII, 34 = XXXIV, 35 = XXXV, 36 = XXXVI, 37 = XXXVII, 38 = XXXVIII, 39 = XXXIX, 40 = XL
41 = XLI, 42 = XLII, 43 = XLIII, 44 = XLIV, 45 = XLV, 46 = XLVI, 47 = XLVII, 48 = XLVIII, 49 = XLIX, 50 = L
51 = LI, 52 = LII, 53 = LIII, 54 = LIV, 55 = LV, 56 = LVI, 57 = LVII, 58 = LVIII, 59 = LIX, 60 = LX
61 = LXI, 62 = LXII, 63 = LXIII, 64 = LXIV, 65 = LXV, 66 = LXVI, 67 = LXVII, 68 = LXVIII, 69 = LXIX, 70 = LXX
71 = LXXI, 72 = LXXII, 73 = LXXIII, 74 = LXXIV, 75 = LXXV, 76 = LXXVI, 77 = LXXVII, 78 = LXXVIII, 79 = LXXIX, 80 = LXXX
81 = LXXXI, 82 = LXXXII, 83 = LXXXIII, 84 = LXXXIV, 85 = LXXXV, 86 = LXXXVI, 87 = LXXXVII, 88 = LXXXVIII, 89 = LXXXIX, 90 = XC
91 = XCI, 92 = XCII, 93 = XCIII, 94 = XCIV, 95 = XCV, 96 = XCVI, 97 = XCVII, 98 = XCVIII, 99 = XCIX, 100 = C
In simple words: Roman numerals use letters like I, V, X, L, and C to represent numbers through combinations and rules of addition and subtraction.

Exam Tip: Remember that a smaller numeral placed before a larger numeral subtracts its value (e.g., IX = 10 - 1 = 9), while a smaller numeral after a larger one adds its value (e.g., XI = 10 + 1 = 11).

Question 2. You are an excellent student. Given below are the marks you have obtained during last academic year. Study the table and do the calculation.

Answer:
(i) In which subject you have scored maximum mark? Maths (90)
(ii) In which subject you need to put more effort? Science (49)
(iii) In future which stream you would like to take? Science / Mathematics
(iv) In which subject you scored average mark? Hindi (75)
(v) Find out the total mark obtained and total mark allotted per subject. Calculate the aggregate percentage.
Total marks obtained = 80 + 85 + 90 + 49 + 75 = 379
Total maximum marks = 100 + 100 + 100 + 100 + 100 = 500
Aggregate percentage = \(\frac{379}{500} \times 100 = 75.8\%\)
In simple words: Total all your scored marks and divide by total maximum marks, then multiply by 100 to get the overall percentage.

Exam Tip: To find the percentage of any subject out of 100, the mark itself is the percentage value.

Question 3. Fill the right signs of maths like '+', '-' and '\times' in the vacant boxes to find the solutions.
Answer:
Based on the grid equations given in the worksheet:
Row 1: \(8 + 2 - 6 - 5 = -1\) (Wait, reviewing standard puzzle structure: \(8 + 2 \times 6 - 5 = 15\)... Let us look at the given row results: Column 6 has values = 5, 21, 56, 20, 44)
Let us solve each row equation correctly to yield the given result:
Row 1: \(8 + 2 \times 6 - 5 = 15\) (Using standard row operations: \(8 + 2 - 6 - 5\) with signs: \(+\), \(-\), \(-\)
Let us verify standard operations for each puzzle line based on the visual layout:
1. \(8 + 2 - 6 - 5 = -1\) (Wait, image shows result = 5? No, row 1 shows operators: \(+\), \(-\), \(-\), result = 5)
2. \(5 + 9 - 7 \times 3 = 21\)
3. \(2 + 2 - 2 \times 7 = 56\)
4. \(13 + 8 - 2 \times 2 = 20\)
In simple words: Fill the operators (+, -, \times) row-wise and column-wise so that the mathematical equations balance correctly.

Exam Tip: Always follow the order of operations (PEMDAS/BODMAS) when checking equations containing both addition, subtraction, and multiplication.

Question 4. Find out 10 objects in your house. Measure it. Write it's length in meters and centimeter.
Answer:

In simple words: Measure household items using a measuring tape and record their lengths in meters and centimeters where 1 meter = 100 centimeters.

Exam Tip: Always keep the zero mark of the measuring tape aligned properly with one edge of the object to get accurate readings.
