Assignment II
1. A hair dryer cost Rs 5400 including 8% VAT. Find the price before VAT.
Show answer
Answer: Price before VAT = 5400 x 100/108 = Rs 5,000.
Teacher's Note: Use the key term in your answer.
2. Divide: (i) x² + 5x + 6 by x + 3 (ii) 3x² - 4x - 4 by 3x + 2 (iii) 2x³ + 7x² - 9 by x + 3.
Show answer
Answer: (i) x² + 5x + 6 = (x + 2)(x + 3), so the quotient is x + 2. (ii) 3x² - 4x - 4 = (3x + 2)(x - 2), so the quotient is x - 2. (iii) The quotient is 2x² + x - 3 and the remainder is 0.
Teacher's Note: Give an example if the question allows.
3. 3(iii). Solve and check: 6(3m - 1) + 3(2m + 3) = 1 - 7m.
Show answer
Answer: 18m - 6 + 6m + 9 = 1 - 7m, so 24m + 3 = 1 - 7m and 31m = -2, giving m = -2/31.
Teacher's Note: Write a short, clear answer.
4. Find the compound interest on Rs 18,000 at 10% per annum for 3 years.
Show answer
Answer: A = 18000 x (1.1)³ = 18000 x 1.331 = Rs 23,958. CI = 23,958 - 18,000 = Rs 5,958.
Teacher's Note: Remember this for your exam.
5. After spending 65% of my money, I had Rs 924 left. How much did I have at first?
Show answer
Answer: 924 is 35% of the money, so the money = 924 x 100/35 = Rs 2,640.
Teacher's Note: Learn this point and write it in your own words.
6. A ceiling fan was bought for Rs 650 and Rs 250 was spent on repair. Find the selling price at a profit of 10%.
Show answer
Answer: Total cost = 650 + 250 = Rs 900. SP = 900 x 110/100 = Rs 990.
Teacher's Note: Use the key term in your answer.
Assignment III
1. A man bought two computers for Rs 45,000. He sold one at a loss of 5% and the other at a profit of 5%, each at the same selling price. Find the cost of each.
Show answer
Answer: Let the costs be x and y. Then 0.95x = 1.05y, so x = 21y/19. Since x + y = 45,000, 40y/19 = 45,000, so y = Rs 21,375 and x = Rs 23,625.
Teacher's Note: Give an example if the question allows.
2. A washing machine has a marked price of Rs 13,000, a discount of 10% and VAT of 10%. Find the amount payable.
Show answer
Answer: After discount: 13,000 x 0.90 = Rs 11,700. With VAT: 11,700 x 1.10 = Rs 12,870.
Teacher's Note: Write a short, clear answer.
3. Meena deposits Rs 8,000 at 12% per annum compounded quarterly. Find the amount after nine months.
Show answer
Answer: The rate per quarter is 3% and the time is 3 quarters. A = 8000 x (1.03)³ = 8000 x 1.092727 = Rs 8,741.82 (about).
Teacher's Note: Remember this for your exam.
4. The population of a town grows 10% per year. Find it after two years if it is now 42,000.
Show answer
Answer: 42,000 x (1.1)² = 42,000 x 1.21 = 50,820.
Teacher's Note: Learn this point and write it in your own words.
5. Factorise 9x² - 30x + 25 - 4y².
Show answer
Answer: 9x² - 30x + 25 = (3x - 5)², so the expression = (3x - 5)² - (2y)² = (3x - 5 - 2y)(3x - 5 + 2y).
Teacher's Note: Use the key term in your answer.
6. Divide x² + 5x - 24 by (x + 8).
Show answer
Answer: x² + 5x - 24 = (x + 8)(x - 3), so the quotient is x - 3.
Teacher's Note: Give an example if the question allows.
7. Factorise x⁸ - y⁸.
Show answer
Answer: x⁸ - y⁸ = (x⁴ - y⁴)(x⁴ + y⁴) = (x - y)(x + y)(x² + y²)(x⁴ + y⁴).
Teacher's Note: Write a short, clear answer.
8. Factorise a⁴ - (2b + c)⁴.
Show answer
Answer: = [a² - (2b + c)²][a² + (2b + c)²] = (a - 2b - c)(a + 2b + c)(a² + (2b + c)²).
Teacher's Note: Remember this for your exam.
9. The numerator of a fraction is 4 less than its denominator. If 3 is subtracted from the numerator and 5 added to the denominator, the fraction becomes 1/4. Find the fraction.
Show answer
Answer: Let the denominator be d. Then (d - 7)/(d + 5) = 1/4, so 4d - 28 = d + 5 and d = 11. The fraction is 7/11.
Teacher's Note: Learn this point and write it in your own words.
10. The tens digit of a two-digit number is three times the ones digit. The number plus the number with reversed digits is 88. Find the number.
Show answer
Answer: Let the ones digit be u, so the tens digit is 3u. The number is 31u and the reversed number is 13u. Then 44u = 88, so u = 2 and the number is 62.
Teacher's Note: Use the key term in your answer.
11. Solve and check: m/2 + 6 = m - 8.
Show answer
Answer: m/2 + 6 = m - 8 gives 14 = m/2, so m = 28. Check: 14 + 6 = 20 and 28 - 8 = 20.
Teacher's Note: Give an example if the question allows.
