ATQ, Let the age of A = 21a B’s present age = 12a C’s present age = 28a D's present age = 28a-24 Total age of A, B, C and D = 60.75×4 = 243years 21a+12a+28a+28a-24 = 243 89a = 267 a = 3 The age of 'A' = 21×3 = 63 years
25 × 5 - ?% of 150 = 102 - 2
25% of 1600 – 152 = ? × 5
15% of 695 – 12.5% of 250 =? – 1200
5 × 14 + 100 ÷ 4 = 62 + ?
36% of 640 – 12.5% of 352 + 25% of 640 = ? – 48% of 432
(60/15) × 25 + 152 – 18% of 200 = ?2
115% of 40 + 3 × 4 = ? × 11 – 8
If √3n 729, then the value of n is equal to:
82.3 × 644.7 × 723.4 × 815.85 = 72?
Find the value of the following expression:
