Question

The difference of two numbers is15. If the sum of 3 times the first number and two times the second turns out to be 90 then the sum of these two numbers would be equal to then the sum of these two numbers will be equal to

Answer 1

let the two no. are a and b








ATQ

a - b = 15 ________ {1}


multiply equation {1} with 2


2a - 2b = 30 ________{2}



3a + 2b = 90 ________{3}




equation {2} + {3}


5a = 120


a = 24

then
b = 9


a + b = 33
