Check option A, –, ×, +, ÷, =
Given:
101 * 32 * 4 * 5 * 7 * 128
After interchanging,
101 - 32 × 4 + 5 ÷ 7 = 128
Here, 5 is perfectly not divisible by 7.
So, its not correct option.
Check option B, –, ÷, +, ×, =
Given:
101 * 32 * 4 * 5 * 7 * 128
After interchanging,
101 - 32 ÷ 4 + 5 × 7 = 128
101-8+35=128
128=128
So, its correct option.
Check option C, ÷, +, ×, –, =
Given:
101 * 32 * 4 * 5 * 7 * 128
After interchanging,
101 ÷ 32 + 4 × 5 - 7 = 128
Here, 101 is perfectly not divisible by 32.
So, its not correct option.
Check option D, +, ×, –, ÷, =
Given:
101 * 32 * 4 * 5 * 7 * 128
After interchanging,
101 + 32 × 4 - 5 ÷ 7 = 128
Here, 5 is perfectly not divisible by 7.
So, its not correct option.
Thus, option B is correct.
