52 − 36 + 141 × 63 ÷ 47
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 52 and 36
The given equation is: 52 − 36 + 141 × 63 ÷ 47
Checking each options one by one:
1. 141 and 52
141 − 36 + 52 × 63 ÷ 47
= 141 − 36 + 52 × 1.34
= 141 − 36 + 69.70
= 174.7
174.7 is not equal to 173.
2. 47 and 63
52 − 36 + 141 × 47 ÷ 63
= 52 − 36 + 141 × 0.746
= 52 − 36 + 105.19
= 121.19
121.19 is not equal to 173.
3. 52 and 36
36 − 52 + 141 × 63 ÷ 47
= 36 − 52 + 141 × 1.34
= 36 − 52 + 189
= 173
173 is equal to 173.
Hence, option 3 is the correct option.
