Question

Mayank and Manoj started a business with investing capital in the ratio of 8:15. After 4 months, Mayank reduced his (1 )/(4 ) portion of the capital and after 7 months, Manoj added his (1 )/(5 ) portion of the capital. If the total profit at the end of the year is Rs. 8,250, what would be Manoj’s share in it? 

A Rs. 5580 Correct Answer Incorrect Answer
B Rs. 6650 Correct Answer Incorrect Answer
C Rs. 5850 Correct Answer Incorrect Answer
D Rs. 6850 Correct Answer Incorrect Answer
E None of these Correct Answer Incorrect Answer

Solution

Let the Mayank’s capital = 8 x Manoj’s capital = 15 x Total profit = Rs 8,250  According to the question, Total capital invested by Mayank = 8 x ×4+8 ×(8x-(8x )/4)  = 32x + 48x = 80x  Total capital invested by Manoj = 15 x ×7+5 ×(15x+(15x )/5)  = 105x + 90x = 195x  Share of Mayank and Manoj = 80 x : 195 x  Share of Manoj = (8,250  )/(275 )× 195 = Rs. 5,850
