Question

compound ratio of 3.5 and 4.6​

Answer 1

Solution:-

We have,

Compound ratio of 7:5 and 8:x=84:60

7×x:5×8=84:60

7x:40=84:60

Product of extremes = product of means

Product of extremes = product of means⇒7x×60=40×84

$\frac{40 \times 84}{60} = 7x$

$7x = 56$

$x = 8$

Hence, this is the answer.
