Question
Monthly income of A and B is Rs. (x + 1500) and Rs. x,
respectively. If monthly income of A is increased by 12.5% while that of B is decreased by 25% then the ratio of their respective income becomes 9:5, respectively. Find the monthly income of A.Solution
According to question; {1.125 × (x + 1500)}/(0.75 × x) = 9/5 => 5x + 7500 = 6x So, x = 7500 So, monthly income of A = x + 1500 = 7500 + 1500 = Rs. 9000
(√780 + 111.98) ÷ 6.95 + 39.95% of 179.98 = ?
What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)...
1120.04 – 450.18 + 319.98 ÷ 8.06 = ?
660 × ? + 495.85 - 60% of 9650 = 37.5% of 7200
(462.23 × 127.84 ÷ 153.88) ÷ √(31.98 × 7.92) = ? ÷ 15.15
(9.013 – 15.04) = ? + 9.98% of 5399.98
17.06 2 + √36.08 – (4.04/2.99) × 3.02 × 4.92 = ? × 4.99
