Options

A. `17:23`
B. `5:8`
C. `17:22`
D. `18:23`

Answer

D

Explanation

Total supply from Jhelum and underground water
`=720xx((12+6)xx18)/(100)=129.6` million litres
Consumption of Yamuna water for domestic purposes
`=720xx(40)/(100)xx(40)/(100)=115.2`
Consumption of Ganga water for agriculture purposes
`=720xx(35)/(100)xx(20)/(100)=50.4`
`:.` Required ratio
`=(129.6)/((115.2+50.=)165.6)=(18)/(23)=18:23`
`[3xx3xx2xx2" is common".]`
