Correct option is D
Given:
Profit ratio of P and Q = 25:26
Ratio of invested money of P and Q = 5:13
Formula Used:
Profit = Time × Investment
Solution:
Let P invested his money be x months, then
According to the question
5 x×: 13 × 6 = 25:26
5x/78 = 25/26
x = 25/26×78/5
⇒ x = 15
Therefore, P invested his money 15 months.
