a and b start a business jointly. a invests rs 16000 for 8 month and b remains in the business for 4 months. out of total profit, b claims 2 / 7 of the profit. how much money was contributed by b?
divide(multiply(multiply(16000, 8), divide(8, 4)), multiply(4, add(4, const_1)))
b claims 2 / 7 of the profit a claims remaining 5 / 7 of the profit = > a : b = 5 / 7 : 2 / 7 = 5 : 2 let the money contributed by b = b then a : b = 16000 × 8 : b × 4 therefore , 16000 × 8 : b × 4 = 5 : 2 16000 × 8 × 2 = b × 4 × 5 16000 × 2 × 2 = b × 5 3200 × 2 × 2 = b b = 12800 answer is a .
