Question

75 is divided into two part so that four times the smaller part is equal to the bigger part the smaller number is

Answer 1

Let the smaller part be a

Bigger part = 4a

According to question,

a + 4a = 75

=> 5a = 75

=> a = 15

Smaller part = 15

Larger part = 4 × 15 = 60

Answer 2

Let parts are ( x ) and ( y )


According to the question :

x = 4y




Now,

Their sum = 75

=> y + x = 75
=> y + 4y = 75
=> 5y = 75
=> y = 15





Parts are :
15
4(15) = 60
