The ratio between the quantities 6 months and 1 year 8 months is -

A

`2 : 5`

B

`3 : 10`

C

`10 : 3`

D

`5 : 2`

Text Solution

Verified by Experts

The correct Answer is:
B
1 year 8 months = ` (1 xx 12 + 8)` months
= `(12 + 8)` months = 20 months
` :. " 6 months : 20 months " = "6 months"/"20 months" = 3/10 = 3 : 10`
Hence the required ratio is ` 3 : 10`
` :. ` (b) is correct .
