Answer :-

  • 172.80

Step by step explanation :-

  • Unitary method :-

Cost of 10 balls = 36

Cost of one ball = 36 / 10 => 3.6

Cost of 48 balls = 48 × 3.6

=> 172.80

  • Direct Variation method :-

No. of balls (a)

10

48

Cost of balls ( b)

36

y

Direct Variation ( a / b )

[tex]\sf\longmapsto \: \frac{10}{36} = \frac{48}{y} [/tex]

[tex]\sf\longmapsto 10y = 36 \times 48[/tex]

[tex]\sf\longmapsto 1 0y = 1728[/tex]

[tex]\sf\longmapsto y = \frac{1728}{10} [/tex]

[tex]\sf\longmapsto 172.80 \: rupees[/tex]

Cost of 48 balls is 172.80 rupees

Hope it helps~
