$\large{\dag\:{\underline{\underline{\frak{\pmb{\red{Answer:-}}}}}}}$

Cricket = 55%
Football = 30%
Other games = Remaining (?)

So, the percent of people who like <u>other games</u> equals:

= 100 – (55 + 30)

= 100 – 85

= 15%

<u>If </u><u>the </u><u>total </u><u>no.</u><u> </u><u>of.</u><u> </u><u>people</u><u> </u><u>is </u><u>6</u><u>0</u><u>,</u><u>0</u><u>0</u><u>,</u><u>0</u><u>0</u><u>0</u>:

★ Cricket

= 60,00,000 × 55/100

= 33,00,000

★ Football

= 60,00,000 × 30/100

= 18,00,000

★ Other sports

= 60,00,000 × 15/100

Suppose y varies directly as x², and y = 160 when x = 4. Find y when x = 6.

labwork [276]

<u>Finding the constant of proportionality</u> :

y = kx²
160 = k(4)²
k = 10

<u>Finding y when x = 6</u> :

y = 10(6)²
y = 10(36)
y = 360

The value of y is <u>360</u> when x = 6.
