If 2¼ + p = 7¾ What number does p represent?

(a)5 1/2 (b)10 (c)9 1/2 (d)5 1/4

EXPLANATION:'Collect like terms and solve

p = 7¾ - 2¼

p = 5 ¾ - ¼

p = 5 2/4

p = 5½

(a)7/13 (b)13/20 (c)7/20 (d)7

EXPLANATION:

Two brothers shared 35 oranges in the ratio 3:4. If the younger brother took the smaller share, how many oranges did he take?

(a)20 (b)42 (c)15 (d)5

EXPLANATION:Seems you have not mastered the art of solving ratio.

First step, add the ratio (3:4 → 3+ 4=7) to get the total and then express the smaller ratio over the total

3 / 7 x 35

= 15

If 6/x = 3/2. What number does x represent?

(a)9 (b)12 (c)6 (d)4

EXPLANATION:'Practice more questions on algebra.

The first step is to cross multiply (3 x X) = (2 x 6)

3x = 12

divide both side by the value beside the alphabet and that is 3

X = 4

Which of the following gives the prime factor of 60?

(a)2, 3, 5 (b)2, 3, 5, 12 (c)2, 3, 6, 15 (d)2, 5, 6, 10

EXPLANATION:'Break 60 down into factors and pick the prime numbers

60 = 5 x 12

60 = 5 x 3 x 4 ( 12 is broken to 3 x 4)

60 = 5 x 3 x 2 x 2 ( 4 is broken into 2 x 2)

Now in these array of factors, pick out the prime numbers

2, 3, 5

Look of this series below. What number should come next?

3, 4, 7, 8, 11, 12, ____

(a)16 (b)15 (c)13 (d)14

EXPLANATION:

Which of the following diagrams is the odd one out?

(a)D (b)A (c)B (d)C

If the digits of a number are in increasing order, we can call that number as a GOOD NUMBER. Which of the following option is NOT a good number?

(a)2008 (b)3579 (c)56893478 (d)3478

EXPLANATION:Increasing order means from the smallest to the biggest..2008 did not satisfy the criteria.

1040 + 1040 + 10 + 10 = ?

(a)2280 (b)2100 (c)3000 (d)4080

EXPLANATION:You probably didn\'\t arrange the numbers properly.

Write the numbers from right to left. That means the two 10 will fall under 40 in the arrangement. Now do this and try again

.

Find the value of t /12 = 5/4.

(a)5/16 (b)5 (c)15 (d)10

EXPLANATION:You need to up your skill on this!

Cross multiply ( t x 4) = (5 x 12)

4t = 60 ( now divide both side by 4)

t = 15

A man packed 1584 tins of milk into 66 similar boxes. How many tins of milk did he put into each box?

(a)1518 (b)1650 (c)24 (d)36

EXPLANATION:'Hmmm, I guess you did not interpret the question properly.

SImply divide 1584 by 66. This is because it involves sharing the whole milk into the boxes

1584 ÷ 66 = 24
