A mercury barometer is defective. When an accurate barometer reads `770` mn, the defective one reads `760` mn. When the accurate one reads `750` mn, the defective one reads `742` mn. Then
The reading of the accurate barometer, when defective are reads `752`mm is

A

`760mm`

B

`764mm`

C

`758mm`

D

`761mm`

Text Solution

Verified by Experts

The correct Answer is:
D
`(P_(0)-752)(80)=10xx72impliesP_(0)=761mm`
