Question

if two third of a number , half of same number and one -seven of same number is added to itself , the result is 37 . the number is ...............?

Answer 1

let the number be x.
two third of x = 2/3 x
half of x = x/2
one seventh of x = x/7
2x/3 + x/2 + x/7 = ((2x × 14) + (x × 21) + (x × 6)) ÷ 42 = 37
37=( 28x + 21x + 6x ) ÷ 42
37= 55x /42
x = 37 × 42 / 55
× = 1544/55

Answer 2

Answer:

LET THE UNKNOWN NUMBER BE X.

2X/3+X/2+X/7=37

L.C.M IS EQUAL TO 42

28X/42+21X/42+6X/42=37

55X/42=37

X=37*42/55

X=1554/55

X=28 14/55

THEREFORE THE UNKNOWN NUMBER IS EQUAL TO 1554/55 OR 28 14/55
