Question

Rajesh invested X amount for 6 months, whereas his father invested 2x for 4 months. If the total profit is Rs.21000, then calculate the profit share for Rajesh and his father​

Answer 1

Answer:

his son invested x amount for 6 month

his father 2x in 4 month

x+2x=3x

6+4=10

x=10/3×21000

210000

Answer 2

Given,

• Rajesh invests X amount for 6 months.

• His father invests 2X amount for 4 months.

• Total profit is Rs.21000

To find,

Profit share of Rajesh and his father.

Solution,

Profit will be directly proportional to the amount deposited and the time for which amount is deposited.

Profit  = amount invested*time for which it was invested.

Profit for Rajesh = $6kX$ ( where  is constant of proportionality )

Profit for his father = $8kX$

Now,

Profit earned by Rajesh = $\frac{6kX}{8kX}*21000 = Rs.9000$

Profit earned by his father = $Rs.21000 - Rs.9000 = Rs.12000$

Therefore, Rajesh's share in profit is $Rs.9000$ and his father's share is $Rs.12000$
