ATQ, Let present age of Q = ‘5x’ years So, present age of P = 1.40 × 5x = ‘7x’ years ATQ, {(7x + 7)/(5x + 7)} = (14/11) Or, 77x + 77 = 70x + 98 Or, 7x = 21 So, x = 3 So, present age of P = 7x = 7 × 3 = 21 years Therefore, age of P, 3 years ago from now = (21 – 3) = 18 years
27% of 250 – 0.02% of 1000 is equal to:
(286 ÷ 11 + 14) × 5 = 40 + 25% of ?
72% of 486 – 64% of 261 = ?
116 ÷ 280 of 1/2 + 3/5 × 5/3 = ?
4368 + 2158 – 596 - ? = 3421 + 1262
`2(1/3)` + `4(1/4)` + `4(2/3)` + `8(7/6)` + ? = `4(3/5)xx4(1/2)`
...?% of 140 + 16% of 250 = 62 × 12
