Question

If 640 amount to 768 in 2 year 6 month what will 850 amount to in 3 years at the same rate percent per annum

Answer 1

In this question, only 2 of the terms are given (P=Given, R=Not Given, T=Given)
We have, p=640, amount=768
T=2 yr 6 months
We have this formula here,
To take out rate= 100×SI/P×T
S.I= P-A (768-640)
=100×128×2/640×6 (2yr 6month)
Rate= 20/3
We apply this, to ₹850 one.
SI=P×R×T/100
=850×20×3/100×3
=170
A=SI+P
=170+850
=₹1020
Is this correct? If it is plz mark it as brainliest. If not, then sorry!
