    A) 21%
    B) 21 1/3%
    C) 23 1/13%
    D) 33%
    C) 23 1/13%
    Explanation:
    30/(100+30) * 100

  2. Rani got 30% discount on the marked price of an article and sold it for Rs 8750 with 25% profit on the price he bought. What was the marked price?
    A) Rs 10,000
    B) Rs 12,000
    C) Rs 16,000
    D) Data inadequate
    A) Rs 10,000
    Explanation:
    C.P. = 100/(100+25) * 8750 = 7000
    (100-30)/100 * x = 7000;

  3. A shopkeeper sold a table for Rs. 17,940 with a discount of 8% and earned a profit of 19.6%. What would have been the percentage of profit if no discount was offered?
    A) 24.8%
    B) 25%
    C) 26.4%
    D) None of these
    D) None of these
    Explanation:
    MP=100/(100-8) * 1740 = 19500
    CP= 17940*(100/100+19.6)=15000
    now if no discount given then SP = MP that is 19500
    so profit = 19500-15000 = 4500
    so p%= (4500/15000) * 100 = 30%

  4. 400 persons, working 9 hours per day complete 1/4th of the work in 10 days. The number of additional persons, working 8 hours per day, required to complete the remaining in 20 days is
    A) 200
    B) 225
    C) 250
    D) 275
    D) 275
    Explanation:
    Remaining work = 1 – 1/4 = 3/4
    400 * 9 * 10 * 3/4 = (400+x) * 8 * 20 * 1/4

  5. The sum of money becomes Rs 13,380 after 3 years and Rs 20,070 after 6 years on compound interest. The sum is
    A) Rs. 8,800
    B) Rs. 8,890
    C) Rs. 8,920
    D) Rs. 9,050
    C) Rs. 8,920
    Explanation:
    P [1 + r/100]^3 = 13380
    P [1 + r/100]^6 = 20070
    Divide both equations, u get
    [1 + r/100]^3 = 669/446
    put this value in first eq and solve for P

  6. The sum was put at simple interest at a certain rate of interest for 3 years Had it been put at 2% higher rate, it would have fetched Rs 360 more. Find the sum.
    A) Rs. 6,000
    B) Rs. 6,200
    C) Rs. 6,020
    D) Rs. 7,050
    A) Rs. 6,000
    Explanation:
    let previous rate is r%, new rate (r+2)%
    P*(r+2)*3/100 – P*r*3/100 = 360

  7. A man takes 5 hrs 45 min in walking to a certain place and riding back. He would have gained 2 hours by riding both ways. The time he would take to walk both ways is
    A) 3 hrs 45 min
    B) 7 hrs 30 min
    C) 7 hrs 45 min
    D) 11 hrs 45 min
    C) 7 hrs 45 min
    walking both ways = (walking+riding time) + (gain in hours riding both ways)
    * riding both ways = (walking+riding time) – (gain in hours walking both ways)

  8. A alone can complete a work in 16 days and B alone in 12 days. Starting with A,, they work on alternate days. The total work will be completed in
    A) 12 days
    B) 13 days
    C) 13 5/7 days
    D) 13 3/4 days
    D) 13 3/4 days
    Explanation:
    2 day’s work of A+B = 1/16 + 1/12 = 7/48
    Multiply by 6 both sides,
    12 day’s work of A+B = 42/48
    Work left = 1 – 42/48 = 6/48 = 1/8
    Now on 13th day, its A’ s turn, he does 1/16th work out of remaining 1/8th
    so after 13th day, work left = 1/8 – 1/16 = 1/16
    now on 14th days, B’s turn, he does 1/12th work in 1 day, so remaining 1/16th work in 3/4th day
    so total days 13 3/4

  9. A, B and C can do a piece of work in 36, 54 and 72 days respectively. They started the work but A left 8 days before the completion of work while B left 12 days before the completion. The number of days for which C worked is
    A) 8
    B) 12
    C) 20
    D) 24
    D) 24
    Explanation:
    Let total number of days is x. C worked for all x days.
    (1/72) * x + (1/36) * (x-8) + (1/72) * (x-12) = bb 1

  10. 12 men complete a work in 9 days. After they have worked for 6 days, 6 more men join them. How many days will they take to complete the remaining work?
    A) 2 days
    B) 3 days
    C) 4 days
    D) 5 days
    A) 2 days
    Explanation:
    After 6 days, the work that can be completed by 12 people in 3 remaining days, let that work be completed by (12+6) = 18 people in x days.
    18 * x = 12 * 3
