5
30
48
57​

Answer 1

Given:

Given that y is directly proportional to x,

x    5    48   57

y    30   -      -

To find:

Complete the table.

Solution:

As given, y is directly proportional to x, we have,

y ∝ x

⇒ y = k x

where, k is a constant

From given table, we have,

x    5    48   57

y    30   -      -

Since we have,

y = k x

30 = k × 5

⇒ k = 30/5

∴ k = 6

Now consider, when x = 48

y = k x

y = 6 × 48

∴ y = 288

Now consider, when x = 57

y = k x

y = 6 × 57

∴ y = 342

Therefore, the completed data is,

x      5       48       57

y      30     288    342
