Shikha deposited ₹2000 in a bank which pays 6% simple interest. She withdrew ₹ 700 at the end of the first year . What will be her balance after 3 years? My solution : P1 = ₹2000 R=6% T=1yr SI =( 2000*6*1)÷100 SI = (120) P2 = ₹2000-₹700 = ₹1300 SI = (1300*6*2)÷100 SI = 156 Amt = 1300+156+120 Amt = ₹1576 Other solution P1 = ₹2000 R=6% T=1yr SI =( 2000*6*1)÷100 SI = (120) Amt = 2000 + 120 =₹2120 P2 = 2120-700=1420 SI = (1420*6*2)÷100 SI = 170.4 Amt = 1420+170.4=1590.4 I am not able to understand why do we have to subtract ₹700 from initial amount ₹2000 . Shikha withdrew ₹700 at the end of the first year . |
