Question

Find the value of 'x' if 2, 3, 10, x are in proportion.​

Answer 1

Answer:

15

Step-by-step explanation:

Note: if a, b,c, and d are in proportion then

a/b = c/d

Using above formula

=> 2/3 = 10/x

=> x = (10 × 3)/2

=> x = 15

Answer 2

Answer:

product of extremes = product of means

2× = 3×10

2× = 30

× =30/2

× = 15
