Question

if the ratio of first and second number is 5:6 and the ratio of the second and the third number is 2:3 if the first number is 35 then find the third number

Answer 1

Answer:

let the no. be 5x,6x,2xand3x so

according to question :-

ratio of 1 and 2 = 5x/6x (equation 1)

and ratio of 2and 3 = 2x / 3x (equation 2)

now to equalize equation 2 we will multiply it by 3

so 3(2x/3x) = 2x *3 /3x*3 = 6x / 9x

now if 5x = 35

then 9x = 35/5x *9x = 63

so the third no. is 63

hope you understand plz thank my answer
