P and Q start a shop with a capital of ₹1,50,000 and ₹4,50,000 respectively. After a year, out of the profit of ₹1,60,000, P gets his share of profit plus some money that is not  apart of the profit, as his salary. If P gets a total of ₹70,000, what is the salary (in ₹) he received ?

30,000

P = Rs. 1,50,000

Q = Rs. 4,50,000

After a year, out of profit of Rs. 160000

P gets = Rs. 70,000

The ratio of investment of P and Q = Rs. 1,50,000 :  Rs. 4,50,000)

⇒ 1 : 3

Let the ratio of investment of P and Q be 1x and 3x respectively

⇒ (1x + 3x) = Rs. 160000

⇒ 4x = 160000

⇒ x = Rs. 40000

The share of P = 1x = (1 × 40,000)

⇒ Rs. 40,000

According to the question

P gets a total = Rs. 70,000

Now,

The amount of salary that P received = Rs. (70,000 – 40,000)

⇒ Rs. 30,000
