Question
A invests Rs. 60,000 in a business, and B invests Rs.
80,000. After 6 months, C joins with an investment of Rs. P. At the end of the year, the total profit is Rs. 1,29,600, of which C’s share is Rs. 28,800. What is the value of P?Solution
ATQ, Capital × time: A: 60,000 × 12 = 7,20,000 B: 80,000 × 12 = 9,60,000 C: P × 6 = 6P Divide all by 24,000 to simplify the ratio: A : B : C = 7,20,000/24,000 : 9,60,000/24,000 : 6P/24,000 = 30 : 40 : (P/4000). Let x = P/4000. Then ratio is 30 : 40 : x. Total ratio = 70 + x. C’s share of profit: x / (70 + x) × 1,29,600 = 28,800 So, x / (70 + x) = 28,800 / 1,29,600 = 2/9 => 9x = 2(70 + x) => 9x = 140 + 2x => 7x = 140 => x = 20 Thus P = 4000 × 20 = Rs. 80,000
((12+12+12+12)÷4)/((8+8+8+8+8+8)÷16) = ?
What will come in the place of question mark (?) in the given expression?
(18 × 8 ÷ 12) × 10 = ?
What value should come in the place of (?) in the following questions?
√? + 10 * 18 + 16 * 4 = 280
What will come in the place of question mark (?) in the given expression?
(? ÷ 16) = (20 ÷ ?) X 20What will come in place of the question mark (?) in the following expression?
40% of 150 – ?% of 80 = 25% of 400
? = 0.05% of 12000 + 175% of 4800 – 133Â
√14400 x √8100 - (60)² = ? + (80)²
√(?) ² = √7396 - √6889
74% of 2840 + 80% of 1640 - ?= 47²
