Question
A loss of 10(1/2) % gets converted into a profit of
11(3/5) % when the selling price is increased by Rs 265.20. The cost price (in Rs) of the article is:Solution
Let the CP of the article be 100a. Now, SP for 1st case = 100a - 100a Γ 10(1/2) % = 89.5a SP for 2nd case = 100a + 100a Γ 11(3/5) % = 111.6a According to the question, 111.6a - 89.5a = 265.2 22.1a = 265.2 a = 265.2/22.1 a = 12 So, cost price = 100 Γ 12 Rs. 1200 β΄ The cost price (in Rs.) of the article is 1200. Second method β Given β loss% = 10(1/2) and profit% 11(3/5) Increased selling price = 265.20 Let cost price =100 ATQ- 10(1/2) +11(3/5) = 265.20 21/2 + 58/5 = 265.2 (105 + 116) /10 =265.2 1 =2652/221 = 12 Then CP = 100Γ12 = 1200 Rs
Simplify the following expression:-
32% of 450 + 60% of 150 = ? Γ 9
- Find the value of the expression:
25 + 9 β 8 Γ [10 + 14 β 2 Γ (33 β 18)] (82 + 62 ) Γ 1.25 + 20% of 145 = ? β 40% of 65Β
(2 Γ· 3) Γ (4 Γ· 12) Γ (? Γ· 10) Γ 45 Γ (1 Γ· 5) = (? Γ· 6) + (2 Γ· 5)
(342 β 20% of 5280) = ? Γ· 3
20% of 550 Γ 25% of 80 = ?2 Γ 22
Find the value of.
