Rajeev buys good worth Rs. 6650. He gets a rebate of 6% on it. After getting the rebate, he pays sales tax @ 10%. Find the amount he will have to pay for the goods.

A. Rs. 6576.10/-

B. Rs. 6686.10/-

C. Rs. 6756.10/-

D. Rs. 6876.10/-

Rs. 6876.10/-

=> Rebate = 6% of Rs. 6650 = ( 6 / 100 ) x 6650 = Rs. 399/-

=> Sales Tax = 10% of ( 6650 - 399 ) = ( 10 / 100 ) x 6251 = Rs. 625.10/-

=> Final Amount = 6251 + 625.10 = Rs. 6876.10/-

Two numbers A and B are such that the sum of 5% of A and 4% of B is two-third of the sum of 6% of A and 8% of B. Find the ratio of A : B

A. 3 : 4

B. 2 : 4

C. 4 : 2

D. 4 : 3

4 : 3

5% of A + 4% of B = 2 / 3 ( 6% of A + 8% of B )

=> ( 5 / 100 ) x A + ( 4 / 100 ) x B = 2 / 3 ( ( 6 / 100 ) x A + ( 8 / 100 ) x B )

=> ( ( 1 / 20 ) x A + ( 1 / 25 ) x B ) = ( 1 / 25 ) x A + ( 4 / 75) x B

=> A / B = 100 / 75

=> A / B = 4 / 3 = 4 : 3

Two students appeared at an examination. One of them secured 9 marks more than the other and his marks was 56% of the sum of their marks. What are the marks obtained by them?

A. 13, 22

B. 23, 32

C. 33, 42

D. 43, 52

33, 42

Let their marks be ( x + 9 ) and x

Then, x + 9 = 56 / 100 ( x + 9 + x )

=> 25 ( x + 9 ) = 14 ( 2x + 9 )

=> 3x = 99

=> x = 33

so their marks are 33 and 33 + 9 = 42

=> 33, 42

A batsman scored 110 runs which included 3 boundaries and 8 sixes, What percent of his total score did he make by running between the wickets?

A. 50.45

B. 61.45

D. 49.45

45.45

Number of runs made by running = 110 - ( 3 x 4 + 8 x 6 )

= 110 - 60

= 50

Percentage Required = ( 50 / 110 ) x 100 = 500 / 11 = 45.45%

What percentage of numbers from 1 to 70 has 1 or 9 in the unit's digit?
