The no. Of adel beads to that of claire's beads was the ratio 7 :4 .When adel gave 68 beads to claire the ratio become 25 :41 . How many beads did claire did claire have finally

37 beads

Step-by-step explanation:

Given that:

Adel : Claire = 7 : 4

Let Adel be = A;  &

Let Claire be = C

A: C = 7 : 4

7C = 4A

--- (1)

When Adel gave 68 beads to claire, we have:

C + 68 = 25:41

25(C + 68) = 41A

C + 68 =

--- (2)

Equating (1) and (2) together;

- 187 A = 175 × (-68)

-187 A = - 11900

A = - 11900/ -187

A ≅ 64

From;

C = 36.57

C ≅ 37 beads
