# Bank PO Questions

A) 1/7 | B) 8! |

C) 7! | D) 1/14 |

Explanation:

The 8 letters can be written in 8! ways.

n(S) = 8!

Let E be the event that the letters b,c,d,e always come together when the first 8 alphabets are written down.

Now the letters a, (bcde), f, g and h can be arranged in 5! ways.

The letters b,c,d and e can be arranged themselves in 4! ways.

n(E) = 5! x 4!

Now, the required P(E) = n(E)/n(S) = 5! x 4!/8! = 1/14

Hence the answer is 1/14.

A) 1548 | B) 1348 |

C) 1648 | D) 1748 |

Explanation:

FV1 = Future value of $2000, 1 year later

= PV (1+ i)^n

A) 5 | B) 10 |

C) 15 | D) 8 |

Explanation:

Raj Tarun's age = 0 when he was born.

Then, given his brother is 6 years old.

Then his father is 6 + 32 = 38 when Raj Tarun was born

And his mother is 3 years yonger than his father => so his mother was 35 years old when Raj Tarun was born

and his sister is 25 year younger than his mother

so Raj Tarun's sister was 10 years old when Raj Tarun was born.

A) Rs. 11828.80 | B) Rs. 19828.80 |

C) Rs. 9828.80 | D) Rs. 19328.80 |

Explanation:

Let the sum be Rs. P

P{ ${\left(1+\frac{8}{100}\right)}^{2}$- 1 } = 2828.80

It is in the form of ${\mathit{a}}^{\mathbf{2}}\mathbf{-}{\mathit{b}}^{\mathbf{2}}\mathbf{}\mathbf{=}\mathbf{}\left(\mathbf{a}\mathbf{+}\mathbf{b}\right)\left(\mathbf{a}\mathbf{-}\mathbf{b}\right)$

P(8/100)(2 + 8/100) = 2828.80

P = 2828.80 / (0.08)(2.08)

= 1360/0.08 = 17000

Principal + Interest = Rs. 19828.80

A) Rs. 2000 | B) Rs. 1600 |

C) Rs. 2200 | D) Rs. 2100 |

Explanation:

Let 'x' be the cost price.

Now Marked price = x + 30x/100 = 13x/10

10% discount = 10/100 x 13x/10 = 13x/100

Selling price = 13x/10 - 13x/100 = 117x/100

Given gain = 340

Here gain = 117x/100 - x = 17x/100 = 340 => x = Rs. 2000.

A) 252 | B) 648 |

C) 243 | D) 900 |

Explanation:

Digits are 0,1,2,3,4,5,6,7,8,9. So no. of digits are 10

First all possible case => 9(0 excluded) x 10 x 10 = 900

Second no repetition allowed =>9 x 9 x 8 = 648

Third all digits are same => 9 (111,222,333,444,555,666,777,888,999)

Three digit numbers where two of the three digits are same = 900 - 648 - 9 = 243 ;

A) Nepal | B) Bhutan |

C) Bangladesh | D) Myanmar |

A) 1995 | B) 1955 |

C) 1980 | D) 1969 |
