    =>4^5 /(4^3)^3*4^8 = 4^?
    =>4^5 / 4^9 * 4^8 = 4^?
    =>? = 4

    Option C
    (24*5/?)^1/2 * 4 = 56 + 34 – 10
    =>(120/?)^1/2 *4 = 80
    =>(120/?)^1/2 = 80/4
    =>(120/?)^1/2 = 20
    =>120/? = (20)^2

    Option B
    (484)^1/2 + (1156)^1/2 – 20% of 500 = ? – 16*3
    =>22 + 34 – 100 = ? – 48
    =>56 – 100 + 48 = ?
    =>? = 104 -100
    =>? = 4

     


  6. P and Q started a business by investing Rs 8,000 and Rs 9,000 respectively. After 4 months P withdrew Rs 400 and Q added Rs 400 more. What is the share of Q from the profit of Rs 10,200?
    4560
    4520
    5560
    5000
    5120
    Option C
    10,200?
    8000*4 + 7600*8 : 9000*4 + 9400*8
    116 : 139
    Share of B = 139/(116+139) * 10200 = 5560

     


  7. Vishal lent out a part of Rs. 38800 is lent out at 6% per six months. The rest of the amount is lent out at 5% per annum after one year. The ratio of interest after 3 years from the time when first amount was lent is 5:4. Find the second part that was lent out at 5%.
    22100
    31200
    25050
    28800
    24500
    Option D
    First Part = x
    [x * (0.06)*6] / (388800 – x)*0.05*2 = 5/4
    1.44x = 19400 – 0.5x
    x = 10000
    Second Part = 38800 – 10000 = 28800

     


  8. Krish is now twice as old as Harsh, who is two years older than Vikram. Four years ago, Krish was four times as old as Vikram. How old is Krish now?
    10
    15
    20
    25
    18
    Option C
    Krish=2Harsh– (i)
    Harsh=Vikram+2.-.(ii)
    four years ago
    Krish-4=4(Vikram-4)
    putting (ii) in (iii)
    we get Krish-4 =4(Harsh-2-4)
    sub (i) in above equation we get
    Krish-4=4(Krish /2-6)
    =>Krish=20

     


  9. A Shopkeeper bought 30 kg of rice at the rate of Rs. 40 per kg. He sold 40% of the total quantity at the rate of Rs. 50 per kg. At what price per kg should he sell the remaining quantity to make 25% overall profit?
    20
    30
    40
    50
    60
    Option D
    Total CP of Rice = 30 * 40 = 1200
    40% of Total Quantity = 40% of 30 = 12
    SP = 12*50 = 600
    SP = 1200 * 125/100 = 1500
    SP of Remaining Quantity = 1500 – 600 = 900
    Remaining Quantity = 18kg
    Rice per Kg = 900/18 = Rs. 50

     


  10. A card is drawn from a pack of 52 cards. The card is drawn at random; find the probability that it is neither club nor queen?
    8/11
    7/12
    9/13
    6/17
    5/12
    Option C
    Probability = 1 – [13/52 + 4/52 – 1/52] = 9/13
