1.	If Rihanna deposits Rs 1500 in the school fund at 9 p.c.p.a for 2 years, what is the total amount she will get?
Answer» Here, P = Rs 1500, R = 9 p.c.p.a , T = 2 years ∴ Total interest = (P x R x T)/100 = (1500 x 9 x 2)/100 = 1500 x 9 x 2 = Rs 270 ∴ Total amount = Principal + Interest = 1500 + 270 = Rs 1770 ∴ Rihanna will get a total amount of Rs 1770.

Answer»

Here, P = Rs 1500, R = 9 p.c.p.a , T = 2 years

∴ Total interest = (P x R x T)/100

= (1500 x 9 x 2)/100

= 1500 x 9 x 2

= Rs 270

∴ Total amount = Principal + Interest

= 1500 + 270

= Rs 1770

∴ Rihanna will get a total amount of Rs 1770.
