If A denotes '+', B denotes '×', C denotes '-', and D denotes '÷', then what will be the value of the following expression?
10 B 19 A 10 D 10 C 7 =?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 184.
Given conditions: A denotes '+', B denotes '×', C denotes '-', and D denotes '÷'
Given equation: 10 B 19 A 10 D 10 C 7 =?
After interchanging the expression becomes:
= 10 × 19 + (10 ÷ 10) − 7
= (10 × 19) + 1 − 7
= (190 + 1) − 7
= 191 - 7
= 184
