Answer 1

Answer:

Step-by-step explanation:

Let, Principle be Rs.P  and Rate of interest be R% p.a.

Amount (A)=P(1+100TR​)

Given that,

6300=P(1+1002R​)...............(i)

7875=P(1+40015R​)...............(ii)

∵T=3129​=415​ years

(i)(ii)​⟹(1+1002R​)(1+40015R​)​=63007875​

⟹400+8R400+15R​=6300÷15757875÷1575​=45​

⟹4(400+15R)=5(400+8R)

⟹1600+60R=2000+40R

⟹60R−40R=2000−1600

⟹20R=400

∴R=20 %(Ans)
