Question

a 2 digit number is 4 times the sum of the digits it is also equal yo 3 times thr product of its digits find the number​

Answer 1

Answer:-

24 or 42

Step-by-step explanation:-

Let unit-place digit be x and tenth-place digit be y. then number is x+10y

 

Given : Number equals 4 times of sum of digits,   x+10y = 4(x+y)  or 3x-6y = 0  or x = 2y ....(1)

 

Given: Number equals 3 times product of its digits,  x+10y = 3(xy)  ...(2)

 

By substituting for x from eqn.(1) , eqn.(2) is written as,   12y = 6y2  or y = 2 hence x = 4

 

number is 20+4 = 24
