House rent + clothing + fuel ⇒ 20 + 12 + 15 = 47%
Food ⇒ 30%
Difference = 47 – 30 = 17%Correct Option: B
House rent + clothing + fuel ⇒ 20 + 12 + 15 = 47%
Food ⇒ 30%
Difference = 47 – 30 = 17%

30% = x% of (12 + 18 + 15)%
⇒ 30 = X × 45 100 ⇒ X = 30 × 100 = 200 45 3 = 66 2 % 3
Correct Option: C
30% = x% of (12 + 18 + 15)%
⇒ 30 = X × 45 100 ⇒ X = 30 × 100 = 200 45 3 = 66 2 % 3
