# Divide Rs 10000 in two parts so that the simple interest on the first part for 4 years at 12 per cent per annum may be equal to the simple interest on the second part for 4.5 years at 16 per cent per annum.

Answer :

Given, money = 10000

Money should be divided into two parts, SI on first part for 4yr at 12% and SI on second part for 4.5yr at 16%

Let first part = 7X

Secon part = (10000-x)

⇒ SI1 = =

⇒ SI2 = =

⇒ =

⇒ = (10000 –x)

⇒ = (10000 –x)

⇒ x = 10000-x

⇒ = 10000

⇒ x = 6000

⇒ First part = 6000

⇒ Second part = 10000-x = 10000-6000 = 4000
