Question

The first , second, and fourth terms of a proportion are 217, 112, 32,
find the third term?
​

Answer 1

217 : 112 :: x : 32

217/112 = x/32 (cross multiplication)

217×32 = 112×x

6944 = 112x

112x = 6944

x = 6944/112

x= 62

third no. is 62

Answer 2

Answer: The no's must be in the order of 32, 112, and 217

Step-by-step explanation:

We can write this as, (take 3rd term as x)

32:112::x:217

=> Product of 1st and 4th term= product of middle terms

=> 32*217= 112x

=> x= 32*217/112

=> x= 62..............
