Question

i dont get it ?? i need help please

Answer 1

Ans is option (b).

This is a simple question of 'Simple Interest per Annum (yearly)'

Acc. to the formula for S.I. ,

I = PRT/100

( where, I = interest, P = principle amount (amount you started with), R = rate of interest and T = no. of years)

Here,

P = $1200

R = 1.5%

T = 10

Now, I at the end of 10 years will be

= (1200 * 1.5 * 10) / 100

= 12 x 15

= $180

Therefore, after 10 years She will have P + Interest (after 10 years) right?

So, amount in her account will be 1200 + 180 = $1380
