(3x + 2) (2x - 5) = ax2+kx+n ...............(1)

But (3x + 2)(2x - 5) = 6x2-11x-10........(2)

so by comparing (1) & (2),

we get a= 6, k= -11 , n= -10

(a - n + k) = 6 + 10 - 11 = 5.

From the given data,

when my age is 24, my mothers age is double of my age 

=> 48 yrs is my mothers age

Carcinomas are cancers that begin in tissues lining the inner or outer surfaces of the body where the DNA of the cells become damaged. Lung cancer and one type of skin cancer (squamous-cell carcinoma) are carcinomas.

Hence, the given statement is TRUE.

Let the present ages of Kapil and Avanthi be K & A

Given difference in their ages = K - A = 9 years ...........(1)

After 7 years, K + 7 =  2(A + 7) ......(2)

K + 7 = 2A + 14

K - 2A = 7 ............(3)

K - A = 9 ....(1)

From (1) & (3),

-A = -2

=> A = 2 years

=> K = 9 + 2 = 11 years

Required, age of Kapil after 4 years = 11 + 4 = 15 years.
