Sum of the present ages of A, B, C and D is 72 years. After 3 years ratio of their ages is 5:4:3:2. What is C’s present age?
At present sum of age = 72 years After 3 years sum of age will be, => 5x + 4x + 3x + 2x = 72 + 3 × 4 => 14x = 72 + 12 => x = 84/14 => x = 6 C’s present age = 3x – 3 = 15 years
120.02% of 599.90 + (34.78/20.89) × (47.98) = ?2 – 10.022
(15.87% of 79.98 + 19.69% of 64.22) × 4.83 = ?
? = (5.8)2 + (8.9)2 + (4.7) 2 + 24.7% of 20
(5.013 – 20.04) = ? + 9.98% of 6199.98
?% of (144.31 ÷ 17.97 × 60.011) = 239.98
39.9% of 1720 + 80.2% of 630 = 89.9% of 1280 + ?
45.22% of (71.9 x 5.01) + 69.97 =?
? = 54.89 × 270.08 ÷ 135.17 + 464.35 ÷ 29.03
?% of 549.83 – 18.05 × 31.96 = 44.94% of 479.84 – 13.98 × 33.13
