d) + x - =
Answer »Answer: (b)
Given, 40* 2* 4 * 3 * 8
Let us check all the options one by one.
From option (a), putting the signs in given equation, we get
40 + 2 - 4 ÷ 3 = 8
⇒ 42 - $4/3$ = 8
⇒ 126 - 4 = 24
⇒ 122 = 24
∴ LHS ≠ RHS
So, option (a) is incorrect.
From option (b), putting the signs in given equation, we get
40 ÷ 2 + 4 = 3 x 8
⇒ 20 + 4 = 24
⇒ 24 = 24
LHS = RHS
Hence, option (b) is correct and there is no need to check remaining options.
