If B’s age be x years, then A’s age be (x - 4) years. According to question, => (x – 4)/x = 5/7 => 7x – 28 = 5x => x = 14 Therefore A's age = 14 – 4 = 10 years
What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)...
Solve the given equation for ?. Find the approximate value.
(35.86 × 15.14) ÷ 9 + √(288.89) × 4.03 = ?
...15.35 x (58.25 + 63.98) = ? + 1029.78
44.78% of 715.62 + 1785% of 42.98 = ?
? = 54.89 × 270.08 ÷ 135.17 + 464.35 ÷ 29.03
180.25 × 14.995 ÷ √26 = ? × 5.985
22.002 × 59.995 + 749.996% of 250.08 + 15.005 % of 1999.997 = ? × 12.008 × 10.009
`sqrt623.798` × 24.034 +`sqrt403.898` × 17.907 =?
(13.156)2 + (3.945)2 + (5.903)3 = ?
1224.04 + 4323.69 = ?% of 3200 + 4747.96
