q1
answer
= 8 * (1/2) / [1 - 1/4 - 1/8 - 1/2]
= 4 / [1/8]
= 32 years

q2
16 = b + t
42 = 2b + 3t

(2b + 3t) – 2(b + t) = 42 – 2*16
t = 10
answer = 10 tricycles

q3a
7 monkeys eat 7 bananas in 7 minutes.
1 monkey eats 1 banana in 7 minutes.
answer = 3 monkeys eat 3 bananas in 7 minutes.

q3b
7 / 7 * 7 = 63 / 68x
x = 63 * 7 / 68 = 6.4853(?) = 7 monkeys

q4
is it 1/4? if yes, then answer
= 16 + 16*(1/4) + 16*(1/4)^2
= 16 + 4 + 1
