Correct Answer: 5 and 107
Solution :
Given:
I. 5 × 12 – 15 + 20 ÷ 25
II. 36 + 3 × 2 – 15 ÷ 5
Equation I:
5 × 12 – 15 + 20 ÷ 25
On interchanging the mathematical signs, we get –
= 5 + 12 – 15 × 20 ÷ 25
= 5 + 12 – 12
= 17 – 12
= 5
Equation II:
36 + 3 × 2 – 15 ÷ 5
On interchanging the mathematical signs, we get –
= 36 × 3 + 2 – 15 ÷ 5
= 36 × 3 + 2 – 3
= 108 + 2 – 3
= 110 – 3
= 107
So, the values of equations (I) and (II) are 5 and 107. Hence, the third option is correct.
