Answer:

Beads that Garima's sister has is 93.

Step-by-step explanation:

Given:

Number of beads that Garima and her sister had = 213

When Garima has 66 more beads then Garima has twice as many beads as her sister.

To find: Number of beads that Garima's sister have at first.

Suppose Garima had x beads.

⇒ her sister had (213 - x) beads.

According tot the Question,

x + 66 = 2 (213 - x )

x + 66 = 426 - 2x

x + 2x = 426-66

3x = 360

x = 120

Beads Garima's sister has = 213 - 120 = 93

Therefore, Beads that Garima's sister has is 93.
