Question

Find the principal which yields a C.I. of Rs 1230 in 2 years at 5% p.a.

​

Answer 1

Answer:

Rs. 12300

Step-by-step explanation:

Let principal be x

S.I.= 1230

Rate = 5%

Time =2 yrs.

S.I.= P*T*R/100

1230 = x*5*2/100

1230= x/10

x= 1230*10

x= 12300

Answer 2

Answer:

₹12300

Step-by-step explanation:

CI= ₹1230

T= 2yrs

R= 5%p.a.

SI= PRT/100

= P×5×2/100

= P/10

A= SI + P

= P/10 + P

= 11P/10

CI = A - P

1230 = 11P/10 - P

1230 = (11-10)P/10

1230×10 = 1P

P = ₹12300

Hence, required principal is ₹12300.
