Explanation:

Let the lent at 5% be 'A'

(A x 5 x 1)/100 + [(1500 - A)x 6 x 1]/100 = 85

5A/100 + 90 – 6A/100 = 85

A/100 = 5

Explanation:

Speed of Boy is B = 4.5 kmph

Let the speed of the stream is S = x kmph

Then speed in Down Stream = 4.5 + x

speed in Up Stream = 4.5 - x

As the distance is same,

=> 4.5 + x = (4.5 - x)2

=> 4.5 + x = 9 -2x

3x = 4.5

x = 1.5 kmph

A) Rs. 4680 | B) Rs. 4420 |

C) Rs. 4960 | D) Rs. 5480 |

Explanation:

Let the expenditure on the 95 students be 'x'

Then,

95x + 500 = 120(x – 5)

95x + 500 = 120x - 600

120x - 95x = 1100

25x = 1100

=> x = 44

Therefore, total expenditure of the hostel becomes

95 x 44 + 500 = 4680.
