26. | | 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)45% | | (b)455/11% | | (c)46% | | (d)47% |
|
Answer is: BNumber of run made by running = 110 - [(3 X 4) + (8 X 6)]
Number of run made by running = 110 - 60
Number of run made by running = 50
∴ required percentage = (50/110) X 100% = 455/11%
27. | | 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. The marks obtained by them are: | | (a)39, 30 | | (b)42, 33 | | (c)44, 31 | | (d)38, 31 |
|
Answer is: BLet 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 42 and 33.
28. | | A fruit seller had some apples. He sells 40% apples and still has 420 apples. Originally, he had: | | (a)600 | | (b)700 | | (c)800 | | (d)900 |
|
Answer is: BSuppose originally he had x apples.
Then, (100 - 40)% of x = 420.
⇒ (60/100) X x = 420.
⇒ x = (420 X 100)/60 = 700.
