Question

The weight of 80 identical books is 320 kg. What could be the ratio of weight of one such book?

• A. 10 kg
• B. 5 kg
• C. 15 kg
• D. 20 kg

Answer 1

Answer: (A), (B), (C)

The correct options are
A

10 kg

B

5 kg

C

15 kg

If the weight of 80 identical books is 320 kg.
Required ratio = $\frac{320}{80}$ = 320 : 80
or $\frac{32}{8}$ = 32 : 8
or $\frac{320}{80}$ = $\frac{4}{1}$ = 4 : 1
