The given diagram shows the number of students who failed in an examination comprising papers in English, Hindi and Mathematics. The total number of students who took the test is 500. What is the percentage of students who failed in atleast two subject ?
Number of students who failed at least two subjects
= 10 + 5 + 12 + 12 = 39
Hence, required percentage = 39 500 x 100 = 7.8
If + means -, - means x, x means ÷ and ÷ means +, then

Akbar will turn 50 when his son Jehangir turns 18. What will be Akbar's age when it will be exactly 5 times that of Jehangir?
Let us suppose when jahangir's age will be 5 times that of akabar's age will be 50 - x
Hence jahangir's age wil be 18 - x
Hence (50 - x) = 5(18 - x)
⇒ 50 - x = 90 - 5x
⇒ 4x = 40
⇒ x = 10
Hence akbar's age will be 50 - 10 or 40 years when jahangir's age was 8 years
A classroom has equal number of boys and girls.8 girls left to play Kho-Kho,leaving twice as many boys as girls in the classroom. What was the total number of girls and boys present initially?
Let number of boy and girls in class are x & y
Then, x = 2 (y - 8)
or x = 2y - 16
again, x = y
or 2y - 16 = y
or y = 16
Total Number of boys & girls are 32

Given that x+2 and x-3 are factors of x3 + ax + b, the values of a and b are
Let p(x) = x3 + ax + b
x + 2 is a factor of p(x)
So, p(-2) = 0
(-2)3 + a(-2) + b = 0
⇒ - 8 - 2a + b = 0
⇒ b - 2a - 8 = 0 .....(1)
x - 3 is a factor of p(x)
So, p(3) = 0
(3)3 + a(3) + b = 0
⇒ 27 + 3a + b = 0 .....(2)
Subtract equation (1) from (2) we get 5a + 35 = 0
⇒ 5a = - 35
⇒ a = -7
b = -6
If x = 1 2 (√3 + 1), then the value of 4x3 + 2x2 - 8x + 7 is-
If x = 1 2 (√3 + 1)
⇒ (2x - 1)2 = 3
⇒2x2 - 2x - 1 = 0
∴ 4x3 + 2x2 - 8x + 7
= 2x (2x2 - 2x - 1) + 3 (2x2 - 2x - 1) + 10
= 2x (0) + 3 (0) + 10 = 10
A rectangular park is 200 by 150m. Two cross paths are to be made one parallel to the length and the other parallel to the breadth. The longer path is to be 3 m wide and the shorter is to be 2 m wide. The cost of grassing the remaining part of the park @ Rs. 1000 per ha is
Area of the park minus the paths
= (200 - 3) (150 - 2)
= 197 x 147 sq. m
= 29156 sq. m
The cost of grashing the remaming part of the park = Rs 29156 10000 x 1000
= Rs 2915.6

The average annual income (in Rs.) of certain argicultural workers is S and that of other workers is T. The number of agricultural workers is 11 times that of other workers. Then the average monthly income (in Rs.) of all the workers is:
Let the number of other workers be x
Then, number of agricultural workers = 11x
Total number of workers = 12x
∴ Average monthly income = S x 11x + T x x /12x = 11S + T/ 12

A man ordered 4 pairs of black socks and some pair of brown socks. The price of a black pair is double that of a brown pair. While preparing the bill,the clerk interchanged the number of black and brown pairs by mistake which increased the bill by 50%. The ratio of the number of black and brown pairs of socks in the original order was
Let x pairs of brown socks were ordered
Let P be the price of a brown pair
Therefore price of black pair of sock = 2P
Then 4P + 2Px = 1.5 (xP + 8P)
⇒ 4P + 2Px = 3 2 (xP + 8P)
⇒ 8P + 4Px = 3xP + 24P
⇒ Px = 16P or x = 16
The ratio of the number of black and brown pairs of socks in the original order was 1:4

Find the minimum number of cubes required to construct a cuboid of dimension 20cm x 16cm x 12cm ?
Volume of cuboid = 20 x 16 x 12 = 3840 cm3
Since minimum no. of cubes required
So length of cube = HCF of 20, 16, 12 cm = 4
Volume of each cube = (4)3 = 64cm3
minimum no of cubes = Vol. of cuboid Vol. of cube = 3840 64 = 60
