Question
Monthly income of A is Rs. 3500 and he saves 42% of his
monthly income. If monthly expenditure of A is decreased by 35% while his monthly savings is increased by 35% then find the increase or decrease in his monthly income.Solution
Monthly savings and expenditure of A initially is Rs. 1470 and Rs. 2030, respectively. Monthly expenditure of A now = 0.65 × 2030 = Rs. 1984.5 Monthly savings of A now = 1.35 × 1470 = Rs. 1319.5 Monthly income of A now = 1984.5 + 1319.5 = Rs. 3304 Desired percentage decrease = [(3500 – 3304)/3500] × 100 = 5.6%
18/2 of 3/9 of 2/6 of 69690 = ?
32% of 250 – 16% of 125 = 8% of ?
43.5 × [1/7 × (91 - 49) + 17(1/3)] = ?
108² + 99 X 98² =?
...What will come in the place of question mark (?) in the given expression?
133 ÷ 19 X √576 + ? ÷ 2 = 32 X 7.552% of 400 + √(?) = 60% of 600 - 25% of 400
(18 × 9 ÷ 6) × 3 = ?
50% of (22 x 15) + 205 = ?
(152 × 24 + 2540)/25 = 44464 ÷ ?
