Question

What sum of money will amount to rupees 900 in 4 years at 5% ? (Simple Interest) ​

Answer 1

Answer:

Let the sum of money be Rs y

So Amount = y +[( y x 5 x 4 )/100]

But Amount = Rs 900

⇒ 900 = y +(20y)/100

⇒ 900 = 6y / 5

⇒ y = ( 900 x 5) /6

= Rs 750

Answer 2

Answer:

SI = PRT/100

SI = (900 × 5 × 4)÷100

SI = 9 × 5 × 4

SI = 180

A = P + SI

A = 900 + 180

A = ₹1080
