**Solutions -**

1) d) speed of john=
30km/hr

speed of max=40 km/hr

let the distnace
between p and m =x km

650-x/30 =x/40+3

7x=2240

x=320 km

2) b) let the Boys=
x; Girls= y

23.25= (30x+20y)/x+y

23.25x+23.25y=
30x+20y

6.75x = 3.25y

x/y= 13/27

3) d) Let the present
age of Ranjana and Rakhi be 15x and 17x

15x+6/17x+6 = 9/10

x=2

=age of ranjana after
6 yrs= 15*2+6= 36 yrs

4) e) Distance
Travelled by Salman in 3 minutes

= 3/60× 120 = 6 km

Distance travelled by
Govinda in 3 minutes

= 3/60 × 80 = 4 km

Hence Salman will
have to travel a distance of 10 km before catching up with Govinda.

Relative speed of
Salman to that of Govinda after taking U turn = 120 – 80 = 40 kmph

∴ Time taken by Salman after taking U turn to
Meet Govinda = 10/40 = 15 minutes

Total time taken by
Salman to meet Govinda = (3 + 15)minutes = 18 minutes

5) d) The quantity of
milk in the mixture = 35 × 4/7 = 20 litres

The quantity of water
in the mixture= 35 – 20 = 15 litres

Now, let the quantity
of water added to the mixture be x litres. Then water becomes 60% of the total
quantity of mixture. ∴
Required % of water in mixture

= Total quantity of
water/Total quantity of mixture = 60%

15 + x/35 + x = 3/5

⇒ 75 + 5x = 105 + 3x

⇒ 2x = 30

∴ x = 15 litres.

6) a) Ratio of 1st and 2nd numbers = 3 : 4

Ratio of 2nd and 3rd
numbers = 5 : 6

Let the 2nd number =
5x, third number = 6x

Product of 2nd and
3rd numbers = 4320

5x × 6x = 4320

X

^{2}= 144
x = 12

2nd number = 60, 3rd
number = 72,

1st number = 60/4 × 3
= 45

Sum of three numbers
= 60 + 72 + 45 = 177

7) d) The smallest cube divisible by 16 is 64.

Lets assume the
average salary before the manager's salary is included is x

After addition of
Manager's salary the average increases by 100

We can write down the
above information in form of an equation as:

64x + 9500 = 65 × (x
+ 100)

Solving for x, we get
x = 3000

The final average is
3000 + 100 = Rs. 3100

8) b) The
manufacturer sells the product to retailer, and then retailer sells to the
customer.

Assume manufacturing cost = 100 and
manufacturer profit = x

As Maximum Retail Price (MRP) of a product is
60% above its manufacturing cost,

MRP = 160% of 100 = 160

The retailer gives 15% discount on MRP. So,
customer price is 85% of MRP.

Buyer Price = 85% of 160 = 136

Manufacturer makes x rupees profit, and then
retailer makes 19% profit.

So, 119% of (100 + x) = 136

⇒
119 (100 + x) = 13600

⇒ (100 + x) = 114.28

⇒ x = 14.28

Hence, Manufacturer profit = 14.2%

9) d) Let 1st number
= x + 12, 2nd = x

Average = 19

(x + x + 12)/2 = 19

2x + 12 = 38

2x = 38 – 12

2x = 26

x = 13

1st = 25, 2nd = 13

Ratio = 25 + 2 : 13 +
2

= 27 : 15 = 9 : 5

10) a)

1st : 2nd = 5:6; 2nd
: 3rd = 15:16

1st : 2nd : 3rd = 5 ×
15 : 6 × 15 : 6 × 16

= 75 : 90 : 96

= 25 : 30 : 32

Difference between
the first and the thirst number = 700

32x - 25x = 700

7x = 700

x = 100

Number, 1st = 25 ×
100 = 2500, 2nd = 30 × 100 = 3000, 32 × 100 = 3200

Average = 2500 + 3000
+ 3200/3

= 8700/3 = 2900
