So, let present ages of ‘A’, ‘B’, ‘C’ and ‘D’ be ‘x’, (x + 2) years, (x + 4) years and (x + 6) years, respectively According to question: x + x + 2 + x + 4 + x + 6 = 100 Or, 4x = 88 Or, x = 22 years (Age of A) Present age of ‘C’ = x + 4 = 22 + 4 = 26 years Required sum = 22 + 26 = 48 years
`(sqrt(1296)xx42)/(120+200)` = ?
7(3/6) of 534 + 262 = 61800 - ?

The income of a person is Rs.15000 and his expenditure is Rs.12000. In the next year his income and expenditure is increased by 8% and 13% respectively....
7.4 × 8.2 + 3.5 × 4.5 = ? + 11.5 × 2.5
√(?) ² = √7396 - √6889
? (1/2) = 236 – 25 × 18/2 + 396 ÷ 22
56 × 18 + ? × 21 – 49 × 12 = 63 × 26Â
