Question

if '-' stands for '÷','÷' stands for '×','+' stands for subtraction and '×' for '+',then which of the following equation is correct?

A. 20+8-7÷6×4=20
B. 20-5÷4+6×5=15
C. 20×5-6÷7+4=28
D. 20÷4-8×10+6=36​

Answer 1

Step-by-step explanation:

According to BODMAS Rule

if (-) = (÷)

(÷) = (×)

(+) = (-)

(×) = (+)

20-5÷4+6×5 = 15

change sign according to Question

20 ÷ 5 × 4 - 6 + 5 = 15

4 × 4 - 6 + 5 = 15

16 - 6 + 5 = 15

16 - 1 = 15

15 = 15

Hence option B is the correct answer
