Solution

$I = \frac{P r t}{100} P = \frac{100 \times I}{r \times t} = \frac{100 \times 192}{6 \times 4} = R s 800$

Find the principal, when the following are given.I= Rs. 192Rate = 6% per annum Time = 4 years

I=Prt100P=100×Ir×t=100×1926×4=Rs800

Find the principal, when the following are given.
$I =$ Rs. $192$
Rate $=$ $6 %$ per annum
Time $=$ $4$ years

$I = \frac{P r t}{100} P = \frac{100 \times I}{r \times t} = \frac{100 \times 192}{6 \times 4} = R s 800$
