Present age of ‘A’ = ‘x – 20’ years Present age of ‘B’ = x – 20 + 8 = ‘x – 12’ years So, 1.25 × (x – 20 + 8) = x + 8 => 1.25 (x – 12) = x + 8 =>1.25x – 15 = x + 8 => 0.25x = 23 => x = 92 Present age of ‘B’ = 92 – 12 = 80 years Present age of ‘D’ = 60 × 2 – 72 = 48 years Desired ratio = (80 – 10):(48 – 10) = 70:38 = 35:19
(√780 + 111.98) ÷ 6.95 + 39.95% of 179.98 = ?
`sqrt623.798` × 24.034 +`sqrt403.898` × 17.907 =?
142.07 + 21.89 – (128.12 ÷ 7.81 – 12.09 × 6.98) = ?
If 4tan4 + 9 – 12tan2 = 0, then find the value of cot.
16.11 × 9.96 – (238.19 – 64.04 × 2.18) = ?
65.22 of 359.98% + 459.99 ÷ 23.18 = ?
619.97 ÷ 20.01 X 124.99 ÷ 24.91 = ?
