##### 3. Question

1 pointsIf ‘–’ stands for division, ‘+’ for

multiplication, ‘÷’ for subtraction

and ‘×’ for addition, which one of

the following equations is correct?

(2) 6 + 20 – 12 ÷ 7 × 1= 62

(3) 6 – 20 ÷ 12 × 7 + 1 = 57

(4) 6 + 20 – 12 ÷ 7 – 1 = 38CorrectOption (1)

Given expression

6 ÷ 20 × 12 + 7 – 1 = 70

After conversion

6 – 20 + 12 × 7 ÷ 1 = 70

or, 6 – 20 + 84 = 70

or, 90 – 20 = 70

or, 70 = 70IncorrectOption (1)

Given expression

6 ÷ 20 × 12 + 7 – 1 = 70

After conversion

6 – 20 + 12 × 7 ÷ 1 = 70

or, 6 – 20 + 84 = 70

or, 90 – 20 = 70

or, 70 = 70 - Question 4 of 20
