1.
2. By statement – I
M : W = 27 : 13
So, in 80 litres of mixture contain
Quantity of milk [latex]= \frac { 27 } { 40 } \times 80 = 54[/latex] litres
Water [latex]= \frac { 13 } { 40 } \times 80 = 26[latex] litres
By statement – II
If 16 litres of mixture replaced by equal quantity of milk. then in new mixture.
Quantity of milk [latex]= \frac { 4 } { 5 } \times 80 = 64[/latex] litres
Quantity of water [latex]= \frac { 1 } { 5 } \times 80 = 16[/latex] litres
Again by statement -I Before mixing water.
Milk is litres and water is 18 litres
Statement – II before mixing milk 48 litres and water is 16 litres
Ratio of milk to water in mixture. = 3 : 1
Quantity of milk [latex]= \frac { 3 } { 4 } \times 80 = 60[/latex] litres
Concept Ratio of milk to water is always same in the mixture. It doesn’t depend on Quantity of mixture drawn.

Total time taken = 2 h 15 min
Let speed of y be S km/h
Speed of x be 1.5 S km/h.
Total time taken [latex]= \frac { \text { Total distance } } { \text { Total speed } }[/latex]
[latex]2 \frac { 1 } { 4 } = \frac { 45 } { 2.5 S } \Rightarrow \frac { 9 } { 4 } = \frac { 45 } { 2.5 \mathrm { S } } \Rightarrow = \mathrm { S } = \frac { 45 } { 2.5 } \times \frac { 4 } { 9 }[/latex]
∴ Speed of x = 1.5 \mathrm { S } = 1.5 \frac { 45 } { 25 } \times \frac { 4 } { 9 } = 12 \mathrm { km } / \mathrm { h }
5. (e) 22.5 15
Height [latex]= 50 \times \frac { 1 } { 4 } = 12.5[/latex]
Perimeter = 2 (3x + 2x) = 50
⇒ x = 5
So, area of two any adjacant walls = b× h + l × h = h (l + b)
Total cost of painting on wall = 12.5 × 25 × 450
= ₹ 140625
