Question

find the simple interest of rupess 350 in 3 years at 10 paise per rupee at every six months

Answer 1

The answer will be 210. SI on 1 rupee is 10 paisa. means 10% rate. SI= PxRxT . P = principal amount=350, R=rate=10%, T= period=6 Hence 350x0.1x6=210. T is 6 because their are 6 six months in three years.

Answer 2

simple interest for 6 months =( p×r×t/100)
=350×10×6/100
=35×6
=210 paise or 2 Rs 10paise

We know that 1 year = 12 months
hence, 3 year =12 ×3
= 36 months

now simple interest for 3 years
= 350×10×36 /100
= 35×36
=1260 paise or 12 Rs 60 paise

hope it will helps you. thanks
