Question

the difference between c.i and s.i on certain sum of money is 283.50 find the sum

Answer 1

ylet p = rs 100

then SI = p*r*T/100=rs.45

now CI= A-P

amount = P (1+R/100)^t =rs.152.08

CI=152.08-100= rs.52.08

now difference between si and ci = 52.08-40=12.08

now difference 12.08 principal=rs 100

now difference rs 1 principal= 100/12.08

now difference rs 283.50 principal= rs 2346.84
