Let the original salaries of Ravi and Sumit be Rs 4x and Rs 5x respectively. According to the question, (4x + 6000)/(5x + 6000) = 35/40 ⇒ 160x + 240000 = 175x + 210000 ⇒ 15x = 30000 ⇒ x = 30000/15 = 2000 Current salary of Ravi = 4 × 2000 = Rs. 8000 Current salary of Sumit = 5 × 2000 = Rs. 10000 So, increased salary of Sumit = 10000 + 6000 = Rs. 16000 ∴ Sumit's increased salary is Rs. 16000.
(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?
