Answer:
30 envelopes
Step-by-step explanation:
If the Cost of 135 envelopes is Rs 45, then;
135 envelopes = Rs. 45
To get the amount of envelopes Rs. 10 can buy, we can write;
x = Rs. 10
Divide both expressions
135/x = 45/10
45x = 135 * 10
45x = 1350
x = 1350/45
x = 30
Hence Rs. 10 can purchase 30 envelopes

The bisector of the angle at A (call it AQ) divides the segment BC into segments BQ:QC having the ratio AB:AC. Use this fact to find x.
.. 9:15 = (2x -1):3x
.. 15(2x -1) = 9*3x . . . . . the product of the means equals the product of extremes
.. 30x -15 = 27x
.. 3x = 15
.. x = 5
___
According to the value of x, the bisector AQ divides the triangle into two isosceles triangles: ABQ, ACQ.
