Question
A shopkeeper marked an article Rs. 700 above its cost
price and sold it after giving a discount of 20% and earned a profit of 30%. Find the cost price of the articleSolution
Let cost price of the article is Rs. 100x So, 1.30 × 100x = 0.80 × (100x + 700) Or, 130x = 80x + 560 Or, 50x = 560 Or, x = 11.2 Cost price of the article = 100 × 11.2 = Rs. 1120
A $ B means A X B, A & B means A - B, A % B means A ÷ B and A # B means A + B, then what is the value of 320 & 80 # 120 % 24 $ 50?
Statements:
V ≤ P < S = B; T < U ≤ I = B; N < J < T
Conclusions:
I. J > P
II. N < S
