Question

the sum of 3 consecutive multiples of 5 is 555 then what are the multiples

Answer 1

hello users ......

we have given that :
The sum of 3 consecutive multiples of 5 is 555,

we have to find :
what are the multiples

solution:-
let first multiple of 5 = 5*x 
because these are consecutive then 
second multiple of 5 = 5* (x+1) 
and 
third multiple of 5 = 5* (x+2)

now,
According to condition .
5x + 5(x+1) + 5 (x + 2 ) = 555
=> 5x + 5x+5 + 5x +10 = 555
=> 15x = 555 - 15 
=> 15x = 540 
=> x = 36 

Hence 
first multiple of 5 = 5 * 36= 180
2nd = 5 * (36 +1) = 5 * 37 = 185
and
3rd = 5 * (36 + 2) = 5 * 38 = 190 Answer 

** hope it helps **
