Question
The sum of three numbers is 72. If the ratio of
smallest number to largest number is 1:3, and that of smallest number to second smallest number is 1:2, then find the largest number.Solution
Let the smallest number be 'x' So, second smallest number = 2x And largest number = x × 3 = 3x ATQ: 2x + 3x + x = 72 Or,
6x = 72 So,
x = 12 So, largest number = 12 × 3 = 36

40% of (320 ÷ 4) + 2² X 25 = ? + 42 {(8× 8 + 3 × 39) - 620 ÷ 20} = ?
125 + 64% of 250 = 150 + ?
Compute:- (3/4 of 64) + (2/5 of 50) - 7
What will come in the place of question mark (?) in the given expression?
{ (3/7) of 294 } + { (4/9) of 108 } − {25% of 160} = ?
(160 × 12 - 13 × 20)/(120 × 2 + 2 × 35 + 2 × 11) = ?
