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
What will be the approximate value of the following questions.
(√143.74 + 29.89% of 720.27) × (5/9 of 539.79) = ?
116.90 ÷ (77.81 ÷ 6.06) + 6.32 = (15.12% of ?) ÷ 4.652
(124.901) × (11.93) + 219.95 = ? + 114.891 × 13.90
Monthly income of A is Rs. 66000 out of which he spent 18%, 11% and 21% of his total income in rent, medicine and transportation, respectively. Find his...
(3/7 of 1049.88 + 44.95% of 799.79) ÷ (√168.89 + 24.77% of 400.11) = ?
11.89 × 2.10 × 4.98 × 4.03 ÷ 7.98 of 15.03 = ?
`[(7.99)^2 - (13.001)^2 + (4.01)^3]^2=` ?
12.023 + 32.05 × 16.08 – 84.04% of 2400 = 56.06% of ?
(24.98)2 = ?2 + (14.99)2
