Answer:

Step-by-step explanation:

given P1= principle=rs640

and amount = A1 = rs768

therefore, simple interest = SI1 = amount - principal

= A1-P1 = rs768 - rs640

= rs128

Time= T1 = 2yrs. and 6 months = 2.5 yrs.

S.I= P×R×T/100

therefore, Rate = R1= SI1×100/P1×T1

= rs128×100/rs640×2.5

=rs12800/rs1600

= 8%

principle given again = P2 = rs850

rate% we have find out =R2= 8%

time given = T2 = 3 yrs.

SI2 = P2 × R2 × T2 /100

= 850×8×3/100

= rs204

A = P2 + SI2

= 204+850

= rs 1054
