Solution :
Given:
l. 10 × 6 – 30 ÷ 4 + 20
II. 8 – 4 × 5 + 6 ÷ 2
Let's solve each equation after interchanging the numbers according to the instructions.
On interchanging the numbers 6 and 4 in the first equation, we get –
= 10 × 4 – 30 ÷ 6 + 20
= 10 × 4 – 5 + 20
= 40 – 5 + 20
= 55
On interchanging the numbers 6 and 4 in the second equation, we get –
= 8 – 6 × 5 + 4 ÷ 2
= 8 – 6 × 5 + 2
= 8 – 30 + 2
= –20
Therefore, after solving the given equations the required answer is 55 and –20. Hence, the third option is correct.
