Question : 8 of 100

Marks: +1, -0

What annual payment will discharge a debt of ₹ 6,450 due in 4 years at 5% per annum simple interest ?

Solution:

(b) Let the annual instalment be ₹ x
∴

( x + { x × 3× 5 } /{ 100 } )

( x + { x × 2× 5 } /{ 100 } )

( x + { x × 1× 5 } /{ 100 } )

+ x = 6450
⇒

{ 115 x } /{ 100 } + { 110 x } /{ 100 } + { 105 x }/ { 100 }

+ x = 6450
⇒ 115x + 110x + 105x + 100x = 6450 ×100
⇒ 430x = 6450 × 100
∴ x =

{6450 ×100}/430

= ₹ 1500
