The ages of Rahul and haroon are in the ratio 5:7 four years later there sum of their ages will be 56 what are their present ages
Answers
• Let present age of Rahul be 5M and present age of Haroon be 7M.
» 4 years later.
Age of Rahul = 5M + 4
And age of Haroon = 7M + 4
» Four years later the sum of their age will be 56 years.
=> 5M + 4 + 7M + 4 = 56
=> 12M + 8 = 56
=> 12M = 56 - 8
=> 12M = 48
=> M = 4
_____________________________
Present age of Rahul = 5M = 5 × 4 = 20 years.
Present age of Haroon = 7M = 7 × 4 = 28 years.
_________________ [ANSWER]
✡ 5M + 4 + 7M + 4 = 56
Put value of M = 4 in above equation.
=> 5(4) + 4 + 7(4) + 4 = 56
=> 20 + 4 + 28 + 4 = 56
=> 56 = 56
___________ [HENCE VERIFIED]
Haroon 28 years , Rahul 20 years
Step-by-step explanation:
let the ratios be x
5:7=5x and 7 x
four year later sum of their age is 56
5x+4+7x+4=56
12x+8=56
12x=56-8
12x=48
x=48/12
x=4
5x=(4*5=20)
Rahul =20years
7x=(7*4=28)
Haroon = 28 years
