How to solve compound interest questions quickly?

Answer 1

$\textbf{\huge{\underline{ Hello Mate! }}}$

A = P( 1 + r / 100 )^n

= 1000 ( 1 + 10 / 100 )^2

= 1000 ( 1 + 1 / 10 )^2

= 1000 × 11 / 10 × 11 / 10

= 10 × 11 × 11

= 1210

C.I = A - P

= Rs ( 1210 - 1000 )

= Rs 210

$\textsf{\red{ Hence C.I. will be Rs 210 }}$

$\textbf{ Have great future ahead! }$
