Answer 2

Given :-

• Principal amount = Rs 1500

• Rate = 3%

• Interest = Rs 135.

To find :-

• Time period in which Naira can get interest of Rs 135 on Rs 1500 .

Solution :-

So Naira gains Rs 135 as interest on Rs 1500 at a rate of 3%.

Formula of Simple interest

$\large{ \underline{ \underline{\sf{ \implies \: \frac{P \times R \times T }{100}}}}}$

$\sf{\implies 135 = \frac{1500 \times 3 \times T}{100} }$

$\sf{\implies 135 \times 100 = 1500 \times 3 \times T}}$

$\sf{\implies \: 135 = 45 \times T }}$

$\sf{ \implies \: \frac{135}{45} = T}$

$\sf{\implies T = 3 }$

$\large{ \underline{ \underline{ \sf{Time \: period \: = 3 \: years}}}}$

So Naira gets Rs 135 as interest after 3 years .
