Answers
Answer:
⇒ S.I. for 2 years = Rs. 720.
⇒ S.I. for 2 years = Rs. 720.⇒ S.I. for 7 years = Rs. 1020
⇒ S.I. for 2 years = Rs. 720.⇒ S.I. for 7 years = Rs. 1020∴ S.I. for 5 years = Rs. 1020− Rs. 720= Rs. 300.
⇒ S.I. for 2 years = Rs. 720.⇒ S.I. for 7 years = Rs. 1020∴ S.I. for 5 years = Rs. 1020− Rs. 720= Rs. 300.⇒ S.I. for 2 years =5300×2=Rs.120
⇒ S.I. for 2 years = Rs. 720.⇒ S.I. for 7 years = Rs. 1020∴ S.I. for 5 years = Rs. 1020− Rs. 720= Rs. 300.⇒ S.I. for 2 years =5300×2=Rs.120⇒ Principal=720−120=Rs.600
⇒ S.I. for 2 years = Rs. 720.⇒ S.I. for 7 years = Rs. 1020∴ S.I. for 5 years = Rs. 1020− Rs. 720= Rs. 300.⇒ S.I. for 2 years =5300×2=Rs.120⇒ Principal=720−120=Rs.600∴ The sum is Rs.600.
Answer:
3900
Step-by-step explanation:
To find= Principal
Let it be P
Rate of Interest= 5% p.a
Time = 4 years
Amount = 4680
Amount = Principal+ SI
4680= P + PRT/100
4680= P + Px5x4/100
4680 = P + 20P/100
4680 = P + P/5
4680 = 5P + P/5
4680x5/6= P
3900= Principal
