Rs. 3500
Selling Price = Marked Price * (1- Discount/100)
2975 = M.P. * (1 - 15/100)
2975 = M.P. * (85/100)
2975 * 100/85 = M.P.
Thus, M.P. = 3500

PN = 15 cm
<p>
In triangle RLQ & triangle PLN,
</p>
<p>
1). Angle RLQ = Angle PLN (Vertically Opp. Angles)
</p>
<p>
2). Angle QRL = Angle NPL (Alternate Angles)
</p>
<p>
Thus, the two triangles are similar. (By A.A. Similarity)
</p>
<p>
</p>
<p>
Therefore,
</p>
<p>
RL/LP = RQ/PN = QL/LN
</p>
<p>
2/3 = 10/PN
</p>
<p>
PN = (10*3)/2
</p>
<p>
PN= 15 cm
</p>

Triangle QLP is similar to triangle RLM. (RM = 32/3)
RL/LP = RM/PQ = LM/LQ
2/3 = RM/16
Thus,
RM=32/3
