Question : Directions: Select the correct combination of mathematical signs to sequentially replace the * signs and to balance the given equation.
150 * 3 * 10 * 2 * 7 * 46
Option 1: ÷, +, –, ×, =
Option 2: –, ×, +, ÷, =
Option 3: +, –, ÷, ×, =
Option 4: ×, +, ÷, –, =
Correct Answer: ÷, +, –, ×, =
Solution :
Given:
150 * 3 * 10 * 2 * 7 * 46
Let's check the given options –
First option:
÷, +, –, ×, =
⇒ 150 ÷ 3 + 10 – 2 × 7 = 46
Solving the L.H.S. of the equation –
= 50 + 10 – 2 × 7
= 50 + 10 – 14
= 60 – 14
= 46 = R.H.S.
Second option:
–, ×, +, ÷, =
⇒ 150 – 3 × 10 + 2 ÷ 7 = 46
Solving the L.H.S. of the equation –
= 150 – 3 × 10 + 0.285
= 150 – 30 + 0.285
= 120.285 ≠ 46
Third option:
+, –, ÷, ×, =
⇒ 150 + 3 – 10 ÷ 2 × 7 = 46
Solving the L.H.S of the equation –
= 150 + 3 – 5 × 7
= 150 + 3 – 35
= 118 ≠ 46
Fourth option:
×, +, ÷, –, =
⇒ 150 × 3 + 10 ÷ 2 – 7 = 46
Solving the L.H.S of the equation –
= 150 × 3 + 5 – 7
= 450 + 5 – 7
= 448 ≠ 46
So, only the first option satisfies the given equation. Hence, the first option is correct.
