If A denotes ‘+’, B denotes ‘ב, C denotes ‘−’, and D denotes ‘÷’, then what will come in place of ‘?’ in the following equation?
77 A 23 B 2 A 25 D 5 = 8 B 32 D 4 ? 64
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. A.
Given equation: 77 A 23 B 2 A 25 D 5 = 8 B 32 D 4 ? 64
Given conditions:
A denotes ‘+’
B denotes ‘ב
C denotes ‘−’
D denotes ‘÷’
After interchanging the expression becomes:
= 77 + 23 × 2 + 25 ÷ 5 = 8 × 32 ÷ 4 ? 64
= 77 + 23 × 2 + 5 = 8 × 32 ÷ 4 ? 64
= 77 + 46 + 5 = 8 × 8 ? 64
= 128 = 64 ? 64
= 128 = 64 + 64
Thus, '?' should be replaced by '+'.
Hence, option 2 is the correct answer.
