- Option : D
- Explanation : We know that for any polynedra
F + V - E = 2; where F = number of faces
V = number of verticcs,
E = number of Edges.

⇒ x - z = 2 - y.
- Option : A
- Explanation : Given, Ravi purchase two articles for ₹1500 each.
Total CP = ₹3000.
Ravi gets 6% profit on first article, then SP of 1st article
= 1500 + 1500 x 6/100.
= ₹1590.
After selling 2nd article, he loses 4%. Then, SP of 2nd article
= 1500 - 1500 x 4/100.
= ₹1440.
∴ Total amount after selling of both article
= 1590 + 1440 = ₹3030.
∴ profit % = 30/3000 x 100% = =1 %.
