7/8 of 3/7 of a number is equal to 25% of 45% of another
number. What is the ratio of the first and the second
numbers respectively?
(a) 3 : 7
(b) 9: 10
(c) 3 : 10
(d) 3 : 2
(e) None of these
let the first number be x
and the second number be y
(7/8)((3/7)x)=(25/100)((45/100)y) given
ie.., 21x/56= 9y/80
on solving we get x:y= 3:10
is the answer
let the first number be x
and second number be y
(7/8)((3/7)x)=(25/100)((45/100)y) given
ie.., 21x/56= 9y/80
on solving we get x:y= 3:10
is the answer
( c ) 3 : 10
the answer is 3:10
