Question

Principal =2600,rate=5%,time=8monthsfind interest and amount

Answer 1

Solution :

Principal ( P ) = Rs 2600,

Rate of interest ( R ) = 5%,

Time ( T ) = 8 months

= (8/12) years

= (2/3) years

i ) Simple interest ( I ) = ( PTR )/100

= ( 2600 × 5 × 2 )/( 100 × 3 )

= 260/3

≈ Rs 86.67

ii ) Amount ( A ) = P + I

= Rs 2600 + Rs 86.67

= Rs 2686.67

Answer 2

sir =p*r*t where the time is in years so the answer would be for 8 months it would be 8 by 12 so
si=(2600*5*8)/(12*100)=86.66
amount = principal + simple interest

a=86.66+2600
