Question
A sells an article to B at a profit of 20% and B sells
it to C at a profit of 20%. If C pays ₹504 for it, what was the cost price for A?Solution
Let the CP of A =100. SP of A at the 20% profit =120. SP of A will be CP of B. CP of B =120 Now SP of B at the 20% profit =120×120/100 =144. SP of B will be CP of C. CP of C =144 But ATQ- 144=504 1=504/144=3.5 100 =350.Rs. CP of A =350
Simplify the following expression:-
32% of 450 + 60% of 150 = ? × 9
- Find the value of the expression:
25 + 9 – 8 × [10 + 14 – 2 × (33 – 18)] (82 + 62 ) × 1.25 + 20% of 145 = ? – 40% of 65
(2 ÷ 3) × (4 ÷ 12) × (? ÷ 10) × 45 × (1 ÷ 5) = (? ÷ 6) + (2 ÷ 5)
(342 – 20% of 5280) = ? ÷ 3
20% of 550 × 25% of 80 = ?2 × 22
