Question 7

Sum of GP (a=3, r=3, 4 terms) invested at 5% SI for 3 years. Find interest.
GP sum (a=3, r=3, n=4) = 120. SI at 5% for 3y = 18.0

Question 8

₹1342 and ₹2397 at 6% for 3 years. Ratio of simple interests = ?
SI1=241.56, SI2=431.46, Ratio = 0.56:1

Question 9

In a GP, the 5th term is 162 (a=2, r=3). This amount is invested at 6% simple interest for 3 years. Find the interest earned.
GP: a=2, r=3, term 5 = 162. SI on ₹162 at 6% for 3 years = 29.16

Question 10

Sum of AP (a=3, d=3, n=4) + 4th term of GP (a=5, r=2) = ?
AP sum = 30, GP term = 40. Combined = 70.0
