Question

the ages of Jyoti and Raghu 11 years and 14 years in how many years time will be the product of their ages be 304

Answer 1

Answer:

5

Step-by-step explanation:

Let the no. of years after their product of is 304 be x

Age of Jyoti after x years = 11 + x

Age of Raghu after x years = 14 + x

Now,

(11 + x)(14 + x) = 304

x² + 14x + 11x + 154 = 304

x² + 25x - 150 = 0

x² + 30x - 5x - 150 = 0

x(x+30) - 5(x+30) = 0

(x+30)(x-5) = 0

x = 5 , -30 (-30 will be rejected as ages cannot be negative)

So, ans is 5
