Answer 1

HI HERE IS THE ANSWER

AMOUNT IN 5 YEARS = ( PRINCIPAL +SI FOR 5 YEARS )=Rs. 4160


AMOUNT IN 2 YEATS =( PRINCIPAL + SI FOR 2 YEARS )=Rs. 3224

ON SUBTRACTING WE GET;

SI FOR THREE YEARS =(rs. 4160-3224)=Rs 936


SI FOR 2 YEATS =Rs.(936/3×2)=Rs.624

SUM=( AMOUNT FOR 2 YEARS)-(SI FOR 2 YEARS)

= Rs(3224-624)=Rs2600

NOW ,

PRINCIPAL=Rs2600

SI=Rs.624

TIME=2 YEARS

RATE =100×SI/2600×2
= 100×624/2600×2=12%p.a.
