Q1 Find the Principal when
(a) S.I. = `192
Rate = 6% per annum
Time = 4 years​

Answer 1

Answer:

Given,

Intrest = 192

Rate =6%

Time = 4 yrs.

we have,

I = P*T*R/100

192 = p*4*6/100

192 = 24p/100

192*100 = 24p

19200 = 24p

p = 19200/24

p =Rs.800

Answer 2

Answer:

p=S.I×100÷R×T

P=192×100÷6×4

P=19200÷24

P=800

Therefore principal =800
