Correct Answer - Option 3 : 18 and 24
Checking the given options :
1) 72 and 24
Given equations :
7 + 24 × 3 – 72 ÷ 18 = 58
After interchange the positions of the numbers according to the options.
7 + 72 × 3 – 24 ÷ 18 = 58
7 + 72 × 3 – 1.33 = 58
7 + 216 – 1.33 = 58
223 - 1.33 = 58
221.67 ≠ 58
2) 3 and 7
7 + 24 × 3 – 72 ÷ 18 = 58
After interchange the positions of the numbers according to the options.
3 + 24 × 7 – 72 ÷ 18 = 58
3 + 24 × 7 – 4 = 58
3 + 168 – 4 = 58
171 - 4 = 58
167 ≠ 58
3) 18 and 24
7 + 24 × 3 – 72 ÷ 18 = 58
After interchange the positions of the numbers according to the options.
7 + 18 × 3 – 72 ÷ 24 = 58
7 + 18 × 3 – 3 = 58
7 + 54 – 3 = 58
61 - 3 = 58
58 = 58
4) 7 and 18
7 + 24 × 3 – 72 ÷ 18 = 58
After interchange the positions of the numbers according to the options.
18 + 24 × 3 – 72 ÷ 7 = 58
18 + 24 × 3 – 10.28 = 58
18 + 72 – 10.28 = 58
90 -10.28
79.72 ≠ 58
Hence, '18 and 24' is the correct answer.
