The wheat sold by a grocer contained 10% low quality wheat. What quantity of good quality wheat should be added to 150 kgs of wheat so that the percentage of low quality wheat becomes 5%?

A150 kgs

B135 kgs

C50 kgs

D85 kgs

Nithin ? undefined

Correct answer is: 150 kgs

Explanation:

Good quality content in 150 kgs. of wheat = 90% of 150 = 135 kgs.
In new mixture, low quality wheat is 5%, so good quality wheat 95%
and 5% of the new mixture = 15 kgs.

Therefore, New mixture = \(\frac{15 \times 100}{5}\) = 300 kg.

Therefore, Good quality of wheat added =  \(\left(300 - 150\right)\)= 150 kg.

Salaries of A, B and C are in the ratio of 2 : 3 : 5 respectively. If their salaries were increased by 15%, 10% and 20% respectively what will be the new respective ratio of their salaries?

A3 : 3 : 10

B23 : 33 : 60

C10 : ll : 20

DCant be determined

Nithin ? undefined

Correct answer is: 23 : 33 : 60

Explanation:

Simplest way to understand.

15% increment in A Salary, So,
2*15% = 0.3.

Total Salary of A after increment = 2+0.3 = 2.3.

10% increment in B Salary, So,
3*10% = 0.3.

Total Salary of B after increment = 3+0.3 = 3.3.

20% Increment in C Salary, So,
5*20% = 1.

Total Salary of C after increment = 5+1 = 6.

Ratio of salary of A, B & C after increment.

2.3 : 3.3 : 6.0.

So 23 : 33 : 60 is answer

ARs.26,000

BRs.28,000

CRs.21,000

DData inadequate

Nithin ? undefined

Correct answer is: Data inadequate

Explanation:

Let the earnings of A and B be Rs.4x and 7x respectively.
After 50% increase. A's earnings = 150% of 4x
After 25% decrease, B's earning = 75% of 7x
Ratio = 150% of 4x : 75% of 7x = 8 : 7
But their total earnings are unknown.
Hence A's earnings can't be known.
