The ratio between two numbers is 2:3. If each number is increased by 6, the ratio between then become 4:5, find the difference between numbers.
Let first number be 2x and the second number is 3x. According to the question, => (2x + 6)/(3x + 6) = 4/5 => 10x + 30 = 12x + 24 => x = 3 Required difference = 3x – 2x = x = 3
600.11 ÷ 14.98 x 5.14 – 171.9 = √?
[{(√785) % of 449.85}/(35.89 × 7.14 + 849.89 ÷ 5.12 + 199.78% of 41.09)] = ( 1/? )
12.232 + 29.98% of 539.99 = ? × 5.99
? × 32.91 – 847.95 ÷ √16.4 – 13.982 = √24.7 × 24.04
5555.05 + 500.05 + 5000.005 + 5.005 =?
[15.87% of 599.97 + 40.08 × ?] ÷ 4.04 = 8.082.02
Direction: Solve the following expression and calculate the approximate value.
(278% of 695) ÷ 543 =?
(84.92 + 235.17) ÷ (15.93 × 3.89) = ? ÷ 21.02
13.99% of 299.99 ÷ 7.17 = ? ÷ 16.15
