Select the correct combination of mathematical signs to replace ∗ signs and to balance the given equation.

20 ∗ 3 ∗ 4 ∗ 8

A=, +, ×

B+, ×, =

C=, ×, +

D×, =, +

Answer:

C. =, ×, +

Read Explanation:

Let us check out,

1) 20=3+4×8,False20 = 3 + 4\times{8}, False

20 = 3 + 32

20 ≠ 35 

2) 20+3×4=8,False20 + 3\times{4} = 8, False

20 + 12 = 8

32 ≠ 8

3) 20=3×4+8,True20 = 3\times{4} + 8, True

20 = 12 + 8

20 = 20

4) 20×3=4+8,False20\times{3} = 4 + 8, False

60 = 4 + 8

60 ≠ 12

Hence, ‘=, ×, +’ is the correct sequence.
