`{:(" "circ+circ=10),(" "circ +square+square=10),(circ+square-Delta xx circ= 5 ):}`
then the value of ` Delta` will be

A

1.5

B

2.5

C

3.5

D

7.5

Text Solution

Verified by Experts

The correct Answer is:
A
0 + 0 =10 ........ (1)
`rArr 0 =5`
`0 + square + square = 10....... (2)`
`rArr square = 2.5`
`0 xx square -Delta xx 0 = 5`
`rArr 5 xx 2.5 -Delta xx 5= 5`
`rArr 5(2.5-Delta) = 5`
`rArr 2.5- Delta = 1`
`rArr Delta = 1.5`
