Question

find fhe Difference between si and ci on 2400 rupees for 2years at 5 percent p.a. compounded annually.​

Answer 1

Step-by-step explanation:

SI =

100

P×R×T

SI =

100

2400×2×5

=240

Compound interest:

Interest for first year =

100

2400×5×1

=120

Amount after first year =2400+120=2520

Interest for second year =

100

2520×5×1

=126

Amount after first year =2520+126=2646

Hence compound interest =2646−2400=246

Difference between CI and SI =246−240=6

Answer 2

Principal= ₹2400

Rate= 5% p.a

Time= 2 years

Amount= P(1+R)/100×n

Amount= 2400(1+5)/100²

2400×105÷100×105÷100

₹2646

Compound interest= Amount- Principal

2646-2400

₹246

Principal= ₹2400

Time= 2 years

Rate= 5% p.a

Simple interest= P×R×T÷100

2400×2×5

₹240

Difference between Compound interest and Simple interest:-

246-240

₹6

So we found the difference between simple interest and compound interest that is ₹6

Discount%= Discount÷Marked price×100

Marked price= 100÷100-D%×S.P

Selling price= 100-D%÷100×M.P
