Answers
Answer:
Account in May = 225
Account in June = 150
Account in july = 200
Step-by-step explanation:
Let the account in June = Jn
Account in may M = 1.5 J
Account in July Jl = Jn + 50
As per the 3 months account, Total account = 575
∴ M + Jn + Jl = 575
∴ 1.5Jn + Jn + (Jn + 50) = 575
∴ 3.5Jn + 50 = 575
∴ 3.5Jn = 525
∴ Jn = 525 ÷ 3.5
∴ Jn = 150
M = 1.5Jn = 225
Jl = Jn + 50 = 150 + 50 = 200
∴ Account in may = 225
Account in June = 150
Account in July = 200
Answer:
May = Rs 291.67
June = rs 116.67
July = Rs 166.67
if interpreted 1.5 times rather than 1.5 times more
May = Rs 225
June = Rs 150
July = Rs 200
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
