After interchanging the given two signs what will be the values of equations (I) and (II) respectively?
× and ÷
I. 18 ÷ 3 - 4 × 2 + 7
II. 18 × 3 ÷ 6 - 8 + 4
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 59 and 32.
I. 18 ÷ 3 - 4 × 2 + 7
After interchanging × and ÷
= (18 × 3) - (4 ÷ 2) + 7
= 54 - 2 + 7
= 61 - 2
= 59
II. 18 × 3 ÷ 6 - 8 + 4
After interchanging × and ÷
= (18 ÷ 3) × 6 - 8 + 4
= (6 × 6) - 8 + 4
= 36 - 8 + 4
= 40 - 8
= 32
