Question
P and Q started a business by investing Rs.5000 and
Rs.3000 respectively. After 4 months, Q increased his investment by a certain percentage such that at the end of 1 year, the profit shares of P and Q were equal. By how much percentage did Q increased his investment?Solution
Let the increased investment amount of Q = Rs.x Ratio of profit shares of P and Q = (5000 x 12) : (3000 x 4 + 8y) = 1:1 So, 60000 = 12000 + 8x => x = 6000 Increase in investment of Q = 6000 - 3000 = Rs.3000 Required % = (3000/3000) x 100 = 100%
- What will be come in place of (?) in the given expressions.
√324 + (18 × 5) – 72 ÷ 8 = ? - What will come in place of the question mark (?) in the following questions?
(2⁴ + 6²) ÷ 2 = ? 226 x 15 - 11 x 99 + (41)2 = ?
(43)² - (28)² + (32)² = ?% of 2500
(18 x 3) + (36 x 8) = ? + 10
289 + 896 + 144 – 25% of 1100 =?
What will come in the place of question mark (?) in the given expression?
(40% of ? × 43 ) – 232 = 751
[192 ÷ 6 × 5] ÷ (? + 3) = 20
{(522 – 482 ) ÷ (27 + 73)} × 35 = ?% of 175
55% of ? = 45 + 20 × 6
