Question

1. One student is asked to divide
the two quantities. Instead of doing so the student divides the given number by 5. If the
half of a number by 6 and other half by 4 and then to add
answer is 4 short of the correct answer then the number was
b) 400
c) 480
d) none of these.
a) 320​

Answer 1

Answer:

480

Step-by-step explanation:

let the initial quantity be x

when divided into two parts it become x/2 & x/2

converting into equation,

x/(2*6) + x/(2*4) = [x/5] + 4

x/12 + x/8 = [x/5] +4

taking lcm

[2x+3x]/24 = [x+20]/5

by cross multiplication

25x =24x + 480

25x-24x = 480

x=480
