Select the correct combination of mathematical signs to replace the * signs and to balance the given equation.
41*4*39*73*25*4*30
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. ×,+,−,=, ×,+ .
Given equation: 41*4*39*73*25*4*30
Applying the signs to the equation by chacking all the options one by one,
1. −,×,+,=,÷,+
41 - 4 × 39 + 73 = 25 ÷ 4 + 30
⇒ 41 - 156 + 73 = 6.25 + 30
⇒ 41 - 156 + 73 = 6.25 + 30
⇒ -42 = 36.25
-42 is not equal to 36.25.
2. ×,+,−,=, ×,+
41 × 4 + 39 − 73 = 25 × 4 + 30
⇒ 41 × 4 + 39 − 73 = 25 × 4 + 30
⇒ 84 + 39 − 73 = 100 + 30
⇒ 84 + 39 − 73 = 100 + 30
⇒ 123 − 73 = 130
⇒ 130 = 130
130 is equal to 130.
The equation is balanced. So, no need to check other options.
Hence, option 2 is the correct option.
