Question

If ₹640 amounts to ₹784 in 5/2 year , what will ₹900 amounts to in 5 years at same rate per cent per annum?

Answer 1

Answer:

1305

Step-by-step explanation:

Given Principal amount =P1=Rs.640

and amount A1=784

therefore, simple interest SI1=amount - Principal

=A1-P1 =784-640 =RS.144

Time = T1= 5/2 Years = 2.5 years which means 2 year's and 6 Months =2.5 years

S.I= P XRXT/100

therefore, rate =R1= SI1 X 100/P1XT1

=144X100/640x2.5

=14400/1600

=9%

Principal Given Again =P2=Rs.900

Rate % we have find out =R2=9%

Time Given T2= 5 years

SI2=P2xR2xT2/100

=900x9x5/100

=405

A=P2+SI2

=900+405

=1305
