If the numbers 20 and 28 are interchanged then which of the following equations can be correctly balanced?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 20 + 40 × 28 ÷ 4 – 14 = 214.
Option 3) 20 + 40 × 28 ÷ 4 – 14 = 214
If the numbers 20 and 28 are interchanged;
28 + 40 × 20 ÷ 4 – 14 = 214
28 + 200 - 14 = 214
214 = 214
Thus, option equation 3 can be correctly balanced.
