Answer 1

Answer:

9000

Step-by-step explanation:

Given: I = 3600, R₁ = 8%, Time = 5 years and T₂ = 4 years, R = 10%.

Given that the interest is same.

⇒ PR₁T₁ = 3600 = P₂R₂T₂

⇒ P₁ * 8 * 5/100 = 3600

⇒ 40P₁ = 360000

⇒ P₁ = P₂ = 9000

Therefore, the sum is 9000.

Hope it helps!

Answer 2

3600*10=36000

36000/100=360 for one year then

we get four year

360*4=1440
