Question

Virat and Ajinkya enhanced 69 runs in the score of India, if the score of ajinkya is double than the score of virat. Find that how many runs ajinkya require to complete his half century.

Answer 1

let virat score x run
ajinkya score y run
x+y = 69
also
y=2x
so
x + 2x = 69
3x=69
x=69/3
x=23
virat run = 23
ajinkya = 69-23=46
he needs 4 run for half century

Answer 2

let runs scored by virat be x and runs scored by ajinkya be y, then
According to question
x+y=69
y=2x
x+2x=69
3x=69
x=23
virat=23
no of runs required by ajinkya to complete his half century will be-: 69-23=46
hope it helps...
