Answer 1

RATIO

==============================

Solve:

$\sf \Large \overbrace{\blue{16} \: : \: \underbrace{\green{48} \: : : \: \green{10}}_{ \tiny multiply} \: : \: \blue{x}}^{multiply}$

$\large \implies \sf \Large \blue{16x} = \green{480}$

$\large \implies \sf \Large \frac{ \cancel{16}x}{ \cancel{16}} = \frac{480}{16}$

$\large \implies \sf \Large \therefore \: x = 30$

Answer 2

Answer:

the fourth terms is 30(ans)

Step-by-step explanation:

$find \: the \: fourth \: proportional \: \\ of \: 16 , 48 \: and \: 10 \\ = 16:48 \: and \: 10:x \\ = product \: of \: means \: = product \: of \: extremes \\ = 48 \times 10 = 16 \times x \\ = > x = \frac{48 \times 10}{16} = 30 \\ ∴ the \: fourth \: terms \: is \: 30(ans)$
