After interchanging the given two numbers and two signs what will be the values of equations (I) and (II) respectively?
× and –, 4 and 5
I. 9 ÷ 3 × 6 + 5 – 4
II. 5 – 4 × 3 + 6 ÷ 2
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 17, 20.
Given conditions: × and –, 4 and 5
I. 9 ÷ 3 × 6 + 5 – 4
After interchanging the expression becomes:
= 9 ÷ 3 - 6 + 4 × 5
= 3 - 6 + 4 × 5 = 17
II. 5 – 4 × 3 + 6 ÷ 2
After interchanging the expression becomes:
= 4 × 5 - 3 + 6 ÷ 2
= 4 × 5 - 3 + 3 = 20
