A) 20 | B) 30 |

C) 40 | D) 50 |

Explanation:

The fruit content in both the fresh fruit and dry fruit is the same.

Given, fresh fruit has 68% water.so remaining 32% is fruit content. weight of fresh fruits is 100kg

Dry fruit has 20% water.so remaining 80% is fruit content.let weight if dry fruit be y kg.

Fruit % in freshfruit = Fruit% in dryfruit

Therefore, (32/100) x 100 = (80/100 ) x y

we get, y = 40 kg.

A) Rs. 63548 | B) Rs. 66512 |

C) Rs. 65000 | D) Rs. 67857 |

Explanation:

The discount offered by showroom = 18%

Raghu purchased at Rs. 54540

Then,

The marked price is given by

54540 x 100/82

=~ **Rs. 66,512**

A) 180 | B) 200 |

C) 220 | D) 240 |

Explanation:

5% of 4000

= 5 x 4000/100

= 5 x 40

= 200

Hence, **5% of 4000 = 200.**

A) 8 cms | B) 7 cms |

C) 9 cms | D) 11 cms |

Explanation:

Let the total length of the pencil = **x cms**

From the given data,

'x/8' is black

Remaining part **= x - x/8 = 7x/8**

1/2 of 7x/8 is white

=> 7x/16 is white (Remaining part is 7x/16)

And given that the remaining part is blue and is 3 1/2 cm = 7/2 = 3.5 cm

That remaining part = 7x/16

Therefore,

**7x/16 = 7/2**

x = 16/2 = 8

Hence, **the total length of the pencil = x = 8 cm.**

A) 28% | B) 26% |

C) 24% | D) 22% |

Explanation:

Let the cost price of each mango be Rs. 1

So 50 mangoes costs = Rs. 50

20% Profit on Selling Price of 10 mangoes = Rs. 12

30% Profit on Selling Price of 20 mangoes = Rs. 26

Total = Rs. 38

Loss = 50 - 38 = 12

Loss% = **(12/50) x 100 = 24%.**

A) 60 | B) 85 |

C) 300 | D) 21 |

Explanation:

The given sentence **21 is 35 of what number** means that

21 is 35 % of what number

Let that number be P

=> 35P/100 = 21

35P = 2100

P = 2100/35 = 300/5 = 60

Hence, **21 is 35 of 60.**

A) 5147 kg | B) 4764 kg |

C) 3587 kg | D) 2125 kg |

Explanation:

Mass of zinc ore = 8000 kg

Mass of metal = 60% of 8000 = 4800 kg

Mass of silver in metal = 3/4 x 4800/100 = 36 kg

Mass of zinc = 4800 - 36 = 4764 kg.

A) 23/50 | B) 36/49 |

C) 33/41 | D) 29/47 |

Explanation:

Given

$4\frac{4}{5}\mathrm{of}229.79=\mathbf{?}\mathrm{of}2398.51$

$\frac{24}{5}\mathrm{x}230=?\mathrm{x}2400\phantom{\rule{0ex}{0ex}}\phantom{\rule{0ex}{0ex}}24\mathrm{x}46=?\mathrm{x}2400\phantom{\rule{0ex}{0ex}}\phantom{\rule{0ex}{0ex}}?=46/100\phantom{\rule{0ex}{0ex}}\phantom{\rule{0ex}{0ex}}\mathbf{?}\mathbf{}\mathbf{=}\mathbf{}\frac{\mathbf{23}}{\mathbf{50}}$

A) 3.5 yrs | B) 4 yrs |

C) 4.5 yrs | D) 5 yrs |

Explanation:

From the given data in the question,

$\mathbf{279841}\mathbf{}\mathbf{=}\mathbf{}\mathbf{160000}\mathbf{}\mathbf{x}\mathbf{}{\left(\mathbf{1}\mathbf{+}\frac{\mathbf{15}}{\mathbf{100}}\right)}^{\mathbf{t}}\phantom{\rule{0ex}{0ex}}\frac{279841}{160000}={\left(\frac{115}{100}\right)}^{\mathrm{t}}$

t = 4 years.
