Hi ,
1 )Compound ratio of 4 : 7 and 3 : 5
= ( 4 × 3 ) : ( 7 × 5 )
= 12 : 35 ----( 1 )
2 ) compound ratio of 3 : 7 and 2 : p
= ( 3 × 2 ) : ( 7 × p )
= 6 : 7p -----( 2 )
According to the problem given ,
( 1 ) = ( 2 )
12 : 35 = 6 : 7p
Product of extrems = product of
means
12 × 7p = 35 × 6
p = ( 35 × 6 ) / ( 12 × 7 )
p = 5 / 2
I hope this helps you.
