Answers :

1) Answer: B

Number of bike sold in April = 20/100 * 48000 = 9600

Number of bike sold in August = 9600 * 7/8 = 8400

2) Answer: E

Number of sold bikes in March = 12/100 * 48000 = 5760

Number of unsold bikes in March = 8800 – 5760 = 3040

Required ratio = 5760:3040

= 288:152

= 36:19

3) Answer: A

Required average = (12 + 30 + 16)/300 * 48000 = 9280

4) Answer: D

Number of sold bikes in May = 22/100 * 48000 = 10560

Number of unsold bikes in May = 10560 * 9/11 = 8640

5) Answer: B

Required percentage = 16/20 * 100 = 80%
