= 14x litre

and the quantity of water = 3x litre

Now, In 25-5 litre of mixture the quantity of milk

25-5 x 14

= 21 litre

and the quantity of water

= 4-5 litre

After the replacement,

(3x – 2) x 5 = (17 x -18)

15x -10 = 17*-18
2x = 8
x = 4

Hence, The initial quantity of mixture in the vessel before the replacement

=-+17 x 4
= 68 litre

 

  1. 8. (A) At the end of the year,

Total Investment of A

= 20000×6 + 12000×6 = 192000

Total Investment of B

= 28000×6 + 20000×6 •= 288000

Total Investment of C

= 36000×12 + 8000×6 = 480000

Now, Ratio in profit

= 192000 : 288000 : 480000 = 2:3:5

scheme A is ? x.

x x 14 x 8

100 = 1-12 x

Amount received from scheme A after 14 years

= x + l-12x = 2-12 x

Now, ATQ,

6678 = 2-12*

6678

*         2-12 x 0-21

  1. (A) Suppose the present age of A = x year

and the present age of B = y years

Then, ATQ,

3x -12 lOy -3x

and (x + 8) x j

x + 8 = 2y + 12 x-2y = 4 On solving eq. (1) and (2) y = 10, x = 24

Hence, the present age of B = 10 years.

  1. (B) Total deduction of P

21800 x10         „„„„

= Too + 4720

= 21800 + 28600-6900 = ? 43,500

  1. (D) Total allowance = 3000 + Basic salary

Now,

Net salary = Basic salary

+ Total allowance – Total deduction 25850 = Basic salary + 3000 + Basic salary – 4350 2 x Basic salary

= 25850-3000 + 4350 = 27200

Basic salary = 13600 from eq. (1)

Total allowance of Q
