Match the following Column A to Column B

Text Solution

Verified by Experts

The correct Answer is:
D
e: `(x)/(10)+(x)/(15)+(x)/(30)=3`
`rArr (3x+2x+x)/(30)=30`
`therefore x=15`
a: `1.5t+2.5t+3.5t=70+0.5t`
`rArr 7.5t-0.5t=70`
`rArr 7t=70rArrt=(70)/(7)=10`
b: Let the number be x.
Given that, `(2x)/(3)-(x)/(6)=10`
`rArr(4x-x)/(6)=10`
`x=20`
d: `3x+5gt25-x`
`rArr 3x+xgt25-5`
`rArr 4xgt20rArrxgt(20)/(4)rArr xgt5`.
