Select the correct combination of mathematical signs to replace the * signs and to balance the given equation.
40 * 2 * 4 * 3 * 8

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
? L H S ? R H S
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.
