Question

half a herd of cattle are grazing in the field and two third of remaining are playing nearby the rest 15 are drinking water from pond and find the number of cattle in the herd? ​

Answer 1

Answer:

let the total of camels be x

so, half a herd= 1x/2

the two third= 2/3 x

and let the rest be 15

therefore, x/2+2x/3+15=x

so, 3x/6 + 4x/6 + 90/6 = x ( since the LCM is 6)

let the denominator be multiplied to the RHS, so we get:

3x + 4x + 90 = 6x

7x- 6x + 90=0

x=90

hope this helps you!!
