1.	Product of ramu's age 5 years ago with his age 9 years later is 15 find dramas age
Answer» Step-by-step EXPLANATION: LET PRESENT age of Ramu be x age of Ramu 5 years ago=x-5 age of Ramu 9 years later=x+9 ATQ, (x-5)(x+9)=15 x²+9x-5x-45=15 x²+4x-45-15=0 x²+4x-60=0 x²+10x-6x-60=0 x(x+10)-6(x+10)=0 (x-6)(x+10)=0 x=6 x=-10, rejected as x is age and age cannot be negative therefore present age of Ramu=6 years

Product of ramu's age 5 years ago with his age 9 years later is 15 find dramas age

Answer»

Step-by-step EXPLANATION:

LET PRESENT age of Ramu be x

age of Ramu 5 years ago=x-5

age of Ramu 9 years later=x+9

ATQ,

(x-5)(x+9)=15

x²+9x-5x-45=15

x²+4x-45-15=0

x²+4x-60=0

x²+10x-6x-60=0

x(x+10)-6(x+10)=0

(x-6)(x+10)=0

x=6

x=-10, rejected as x is age and age cannot be negative

therefore

present age of Ramu=6 years
