Let A’s age be x years. B’s age = 3x and C’s age = (5 + x) According to question, => x + 3x + (5 + x) = 40 => 5x = 35 => x = 7 B’s age = 3x = 21 years C’s age = 5 + x = 12 years Difference between the ages of B and C = 21 – 12 = 9 years
(12% of 1250 + 85% of 400) x 10 = ?2
What will come in the place of question mark (?) in the given expression?
(70 × 8 ÷ 10) × 5 = ?
82.3 × 644.7 × 723.4 × 815.85 = 72?
The value of (40 + 3/4 of 32) /[37 + 3/4 of (34-6)] is:
236.23 - 653.23 + 696.23 = ?
7.4 × 8.2 + 3.5 × 4.5 = ? + 11.5 × 2.5
800 + 900 X (3)-2 - ? = 25 X 60 ÷ 2
808 ÷ (128)1/7 + 482 = 4 × ? + 846
30% of 215 + 135% of ? = 469.5
