In May, her account was one and a half times more than her account in June. Her account in July was R 50 more than her account in June. In total, she spent R575 in cellular-phone accounts in the three months.The sum of three consecutive odd numbers is 45. What are the numbers?

Answer 1

Answer:

Step-by-step explanation:

Let say june month account = J

May month account = J + 1.5J = 2.5J

July month account = J + 50

may + june + july = rs 575

J + 2.5J + J + 50 = 575

=> 4.5J = 525

=> J = 525/4d.5

=> J = 116.67

May month account = 2.5 × 116.67 = Rs 291.67

June month account = rs 116.67

July Month account = Rs 166.67

if we say may month = 1.5 J

then

1.5 J + J + J + 50 = 575

3.5J = 525

J = 150

May = Rs 225

June = Rs 150

July = Rs 200
