Question

A sum of * 200 is deposited in a post office at 1 the rate of 5-% simple interest per annum. 2 What will be the total amount after 2 yr ? (a) 220 (b) * 225 (c) 222 (d) * 229​

Answer 1

Answer:

Step-by-step explanation:

• Given sum $=200$, Rate of interest $=5$%, Time period $=2$ years

• Formula for simple interest  $=\frac{PTR}{100}$

On substituting the values, we get

$=\frac{200\times5\times2}{100}$

$=220$

Hence, the total amount after $2$ years will be $220$.

Answer 2

Given,

Amount deposited in post office $P=200$

Simple interest per annum $5$%

$R=\frac{5}{100}=0.05$

Time $=2$ hours

Simple interest $=PTR$

$=200\times2\times0.05$

$= 20$

After $2$ years total amount $= P+SI$

$=200+20=220$

Therefore, total amount after $2$ years is $220$.
