Required average = {(21 × 22) – 32 – 64 + 45 + 9}/21 = 20 years
(3500 ÷ √1225) × √(20.25) = ? ÷ 4
27% of 250 – 0.02% of 1000 is equal to:
(√529 + 63 /8)% of 800 = ?% of 250
The value of [(3√2+2) × (3√2-2)] of 13 + 15 is:
√4096 + √3249 = (?)2
5.5 × 3.2 × 2.3 = ?
15% of 695 – 12.5% of 250 =? – 1200
9 × 40× 242 × 182= ?2
40% are the passing marks. A student gets 250 marks yet fails by 38 marks. What is the maximum marks?
