  • Question 1/5
    1 / -0
    Simplify 4[30+(45+10/2*4-25) +15]
    Solutions

    4[30+(45+10/2*4-25) +15]

    → 4[30+(45+5*4-25)+15]

    → 4[30+(45+20-25)+15]

    → 4[30+(65-25)+15]

    → 4[30+40+15]

    → 4(85)

    → 340

  • Question 2/5
    1 / -0
    Find the square root of 8464
    Solutions

    Step1- Write down the number 8464 as a product of its prime factors.

    8464=2*2*2*2*23*23

    → 24*232

    Step2- the required square root is obtained by halving the values of the powers.

    Hence, =22×231

    → 92

  • Question 3/5
    1 / -0
    Two numbers are in the ratio 6:7. Their L.C.M. is 168. The greatest number is
    Solutions

    let the numbers be 6x and 7x

    LCM of 6x and 7x is=42x

    So the number 168 is divisible by 42

    → 168/42=4

    → The numbers are 4*6=24

    → Second number= 4*7=28

    Hence, the greatest number is 28.

  • Question 4/5
    1 / -0
    What will be the reminder when -34 is divided by 5?
    Solutions
     -34=5*(-6) +(-4)

    Remainder=-4, but it is wrong because remainder cannot be negative.

    So, -34=5*(-7) +1

    → Hence, 1 is the remainder.

  • Question 5/5
    1 / -0
    What will be the number of zeroes in 18!
    Solutions

    factorial of 18 contains 15 and 5, which combined with one even number gives zeroes. Also, 10 is also contained in factorial of 18, which will give an additional zero. Hence, factorial of 18 contains 3 zeroes and the last digit will always be zero.
