Match the statements /expression given i...

Match the statements /expression given in List I with the values given in List II.

Text Solution

Verified by Experts

The correct Answer is:
`d rarr q,t`
`(2ab)/(a+b)=4`
`rArrab=2a+2b`
Now, q=10 -a
and 2q=5+b
`rArr20-2a=5+b`
`rArr15=2a+b` (2)
From (1) and (2),
a(15-2a)=2a+2(15-2a)
`rArr15a-2a^(2)=-2a+30`
`rArr2a^(2)-17a+30=0`
`rArr a=6,5/2` accordingly q=4, `15/2`
`rArrabs(q-a)=2,5`
Note: Solutions pff the remaining parts are given in their respective chapters.
