Question

The third proportional to 9 and 25
(a) 8013
(b) 80
(c) 8017
(0) None of these​

Answer 1

Answer:

O is the right answer

Step-by-step explanation:

none of these

Answer 2

Answer:

None of these

Formula:

The third proportion of a and b = b2/a

Calculation:

Third proportional means number c in a : b = b : c

⇒ Third proportional to 9 and 15 is 9 : 25 = 25 : c

⇒ c = 15

∴ Third proportional to 9 and 25 = 15

we can try another method

=a:b=b:c

=a/b=b/c

$b ^{2} = ac$

$x ^{2} = 9 \times 25$

$x ^{2} = (3 ) ^{2} \times( 5) ^{2}$

x=3×5

×=15
