Jeremy opens a chocolate shop in the city. He pays $1,500 a month for rent and maintenance of the shop. The price of raw materials and manufacturing the chocolates is $6,000 a month. He sells the chocolates individually and in boxes of a dozen. Jeremy understands that his business needs a little time to become a success and decides that he wants to build a customer base initially. He is happy to break even for the first year. After a year, Jeremy prices his chocolates at $3 apiece. He offers a discount of 10% on boxes of chocolate to promote the sale of boxes. How many boxes of chocolate would he have to sell to recover the cost of running the business this year per month? (Assume that he sells no individual chocolates.) A. 188 boxes B. 208 boxes C. 226 boxes D. 232 boxes |
|
Answer» Total expenditure of JEREMY = $1500+6000 = $7500 Now, COST of a box having a DOZEN chocolates = 12×3 = $36 If he gives 10% discount, then cost of each box is 36 - (10%of 36) = $32.4 So, number of boxes = 7500/32.4 = 231.4 = 232 Option (D) |

18. A two digit number is obtained by multiplying thesum of the digits by 8. Also, it is obtained bymultiplying the difference of the digits by 14 andadding 2. Find the number. |
Answer» ANSWER:
GIVEN:
TO FIND:
SOLUTION:Let the digit at tens place be 'X'. Let the digit at once place be 'y'. Original number = 10x+y CASE 1=> 10x+y = 8(x+y) => 10x+y = 8x+8y => 10x-8x +y-8y = 0 => 2x-7y = 0. Muntiplying both sides by 2 => 4x-14y = 0. .....(i) CASE 2.=> 10x+y = 14(x-y)+2 => 10x+y = 14x-14y+2 => 10x-14x+y+14y = 2 => -4x+15y = 2 => -4x+15y = 2 => -4x+15y = 2 ....(ii) Adding eq (i) and (ii) => 4x-14y-4x+15y = 2 => y = 2 putting y = 2 in eq(i) => 4x-28 = 0 => 4x = 28 => x = 7 Original number = 10(7)+2 = 72 |

BUSvo. In a reaction 5.39. of sodium carbonate reacted with 6 g, of ethanoic acid. The product were 2.2 g o!corbon dioxide, 0.9 g. of water and some sodium ethanoate. What is the expected weight of sodiumethanoate? Prove that this date is in agreement with law of conservation of mass. |
Answer» Answer:LAW OF CONSERVATION OF MASS:law of conservation of mass states that the total weight of reactants is equal to the total weight of products formed .Na2CO3 + CH3COOH = H2O+ CO2+CH3COONa(5.39) ( 6g) (0.9g) (2.2) (x)ACCORDING to LAW of CONSERVATION of MASS ,5.39 + 6.0 = 0.9 + 2.2 + x11.39 = 3.1 + x=> x = 11.39 - 3.1 = 8.29g∴ expected weight of sodium ethanoate = 8.29g |

If α and β are zeroes of polynomial 2x²-4x+5.Then find the value of following:(a) α²+β²(b) 1/α+1/βPlease answer fast ...... |
|
Answer» Answer: a) -1 B) 4/5 Step-by-step EXPLANATION: α and β are zeroes of polynomial 2x²-4x+5. So equate the polynomial to 0. 2x^2 - 4x +5=0 Sum of roots = -(coefficient of x)/coefficient of x^2 = α+β Product of roots = (constant)/coefficient of x^2 = αβ Sum of roots=α+β=4/2=2 Product of roots = αβ = 5/2 We need to find α²+β² which can be written as - α²+β²=(α+β)²-2αβ Now put values of αβ and α+β in above equation α²+β²=(2)² - 2(5/2) = 4 - 5 = -1 1/α+1/β can be written as 1/α+1/β=(α+β)/αβ -----------[ By taking LCM as αβ ] Now we know values of α+β and αβ , so by USING those values in above equation we get - 1/α+1/β=2/(5/2) = 4/5 |
