Question

Find p such that 15 : p : : 42 : 6.(please explain the process also.)​

Answer 1

Answer:

Let the p as □ (box)

15 : □ : : 42 : 6

= □ × 42 = 15 × 6

= □ = 90/42

□ = 5

Therefore, p = 5

Answer 2

$\mathfrak{ \large{\blue{ \underline{ \purple{ Given: }}}}}$

$\: \: \: \: \: \: \: \: \: \: \bullet \: \: \: \: \: \: \: { \mathfrak{ \large{15 : p : : 42 : 6}}}$

$\mathfrak{ \large{\blue{ \underline{ \purple{ To \: Find:}}}}}$

• Value of p

$\mathfrak{ \large{\blue{ \underline{ \purple{ Solution: }}}}}$

$\large{ \rm \longmapsto \: \: \: \: \: \: \: \frac{15}{p} = \frac{42}{6}}$

After cross multiplication,

$\large{ \rm \longmapsto \: \: \: \: \: \: \: 42 \times p = 15 \times 6}$

$\large{ \rm \longmapsto \: \: \: \: \: \: \: p = \frac{15 \times 6}{42}}$

$\large{ \rm \longmapsto \: \: \: \: \: \: \boxed{ \red{ \mathfrak{ p = 2.14}}}}$

$\mathfrak{ \large{\blue{ \underline{ \purple{ Hence:}}}}}$

The value of p is 2.14 ( Approx)
