А.
700
B.
750
C. 650
D. 800​

Answer 1

Step-by-step explanation:

Let the tot. no. of people working in an office be x

No. of unmarried people = 490

Percentage of people married = 30%

Percentage of unmarried people = 100 - 30 %

= 70 %

No. of unmarried people = 70% of x

70% of x = 490

70x / 100 = 490

70x = 49,000

x = 49,000 / 70 = 700

x = 700

Answer - 700 people are working in the office
