5. The ratio of the 1^st installment to the last installment is

a) 1:49

b) 10:49

c) 10:39

d) 39:10

Answer 1

l = 1,18,000

a = 1000

d = 100

1. a₃₀ = a + 29d

= 1000 + 29(100)

= 1000 + 2900

= 3900

2. Amount paid by him in the 30 installments = 30/2 [2000 + 2900]

= 15[2000 + 2900]

= 30000 + 43500

= 73500

3. Money remaining to pay after the 30th payment = 118000 - 73500

= 44500

4. a₄₀ = 1000 + 39(100)

= 1000 + 3900

= 4900

5. a = 1000

a₄₀ = 4900

= 1000 : 4900

= 10 : 49

Answer 2

1. a) 3900

2. b) 73500

3. c) 44500

4. a) 4900

5. b) 10 : 49
