To solve: (2 5/4 - 5 1/6 + 3 1/3) / (0.087 + 0.3717 ÷ 0.9) Step 1: Simplify the Numerator Convert each mixed number to an improper fraction: 2 5/4 = 13/4 5 1/6 = 31/6 3 1/3 = 10/3 Rewrite the expression as: 13/4 - 31/6 + 10/3 Find a common denominator (12) and convert: 13/4 = 39/12 31/6 = 62/12 10/3 = 40/12 Now calculate: 39/12 - 62/12 + 40/12 = 17/12 Step 2: Simplify the Denominator The denominator is: 0.087 + 0.3717 ÷ 0.9 First, perform the division: 0.3717 ÷ 0.9 = 0.413 Then add 0.087: 0.087 + 0.413 = 0.5 Step 3: Divide the Numerator by the Denominator Now we have: (17/12) ÷ 0.5 = (17/12) × 2 = 34/12 = 2.833 Answer: The correct answer is A. 2.833 The questions are a bit tricky, you just need to use your brain and stop blaming SOF.

Ans 8:

Chinmay from JSS public school, Noida
Class : Class 5
answer will be 108 because at the top they have given a full square which has perimeter of 32 cm and the rest 3 squares have 24 cm .So 24 24=24 32=108 cm

Ans 9:

Vihaan from K R Mangalam World School Vaishali, Ghaziabad

Explain it properly, man!

Ans 10:

SIDH DALMIA from GEMS MODERN ACADEMY, Dubai
Class : Class 6
It should be 104, as the first square is not overlapping, so it is 32 cm, and the rest are 3 squares of 24 cm, and 24 x 3 =72 and 72 32 = 104. So it is neither of them.
