The table given below shows the total number of Samosa and Kachori sold and the ratio of the number of Samosas to that of Kachoris sold by five different shops A, B, C, D and E.
...view full instructions
Find the difference between the number of Samosas sold by shop B and the total number of Kachoris sold by shop C
Required difference = 100 – 80 = 20
Hence, option C is correct.
Find the ratio of the total number of Samosas sold by shop A to the total number of Kachoris sold by shop C
Required ratio = 150 : 100 = 3 : 2
Hence, option B is correct.
Find the average number of Samosas sold by shop B, C and E
Hence, option A is correct.
A, B and C are three partners in a business. A's share is 3/16 of the profit and C's share is 1/4 of the profit. If B receives Rs. 396, then the amount received by C will be:
A = 3/16
C = 1/4 = 4/16
∴ B = 16 −3 − 4 = 9
9 unit = 396
∴ 4 unit = Rs. 176
12 women can complete a piece of work in 5 days, whereas 3 women and 9 children together can complete the same piece of work in 10 days. In how many days can 36 children complete the same piece of work?
12 women complete the work in 5 days.
So, 36 children will complete the work in 5 days.
The sum of five consecutive even numbers is equal to 230. What is the sum of largest number and the smallest number?
Let the consecutive five even numbers be x, x+2, x+4, x+6, x+8
Sum = x+x+2+x+4+x+6+x+8 = 5x+20
According to given 5x+ 20 = 230
5x=230-20=210
x=210/5 = 42
x+8=42+8=50
50+42=92
Hence option E is correct.
What would be the compound interest obtained on an amount of Rs. 7790 at the rate of 10% per annum after two years ?
Formula for compound interest
Where P: principle amount, r : rate of interest, T : time
Now P = 7790, r = 10 , T = 2
Ram is 3 times of Sham’s age and 1/3rd of Pal’s age. Sum of their ages is 130 years. Find out the age of Sham.
Ratio of Ram to Sham age = 3 : 1
Ratio of Ram to Pal’s age = 1 : 3
Ratio of Sham: Ram: Pal = 1 : 3 : 9
Sum of ages = 130 years (given)
Sham’s age = 130/13 x 1 = 10 years
Find the wrong term in the given series:
5, 8, 12.5, 18.5, 25, 35
The series is
5 + (1.5*2) = 8
8+ (1.5*3) = 12.5
12.5 + (1.5* 4) = 18.5
18.5 + (1.5* 5) = 26
26 + (1.5*6) = 35
so, 26 should be in place of 25.
In the following number series, one of the numbers is wrong. Find out the wrong number.
7, 8, 16, 43, 109, 232, 448
Pattern of the given series is:
7 + 13 = 8 8 + 23 = 16 16 + 33 = 43 43 + 43 = 107 107 + 53 = 232 232 + 63 = 448
Hence, option B is the correct answer.
