Q357: The angles of triangle are 45 ∘ ,60 ∘ find the third angle .

Explanation

Let the triangle be $Δ A B C$
The sum of angles in triangle is $18 0^{\circ}$
$4 5^{\circ} + 6 0^{\circ} + ∠ C = 18 0^{\circ} ∠ C = 180 - 45 - 60 ∠ C = 7 5^{\circ}$

Q359: The mean weight of 6 boys in a group is 48 kg. The individual weights of 5 of them are 50 kg, 45 kg, 49 kg, 46 kg and 44 kg. Find the weight of the sixth boy.

Explanation

Mean weight of $6$ boys $= 48$ kg.
Let the weight of the $6$ th boy be a kg.
$\frac{5 0 + 4 5 + 5 0 + 4 2 + 4 0 + a}{6} = 48$
$= > 227 + a = 288 = > a = 61$
weight of the $6$ th boy $= 61$ kg.

Q355: In a mixture 60 litres, the ratio of milk and water 2:1. If this ratio is to be 1:2, then the quanity of water to be further added is

Explanation

Quantity of milk =(60×32​) litres =40 litresQuantity of water in it =(60−40) litres =20 litresNew ratio =1:2Let the quantity of water to be added further be x litresThen milk : water =(20+x40​)Now, (20+x40​)=21​=> 20+x=80=> x=60

Explanation

Mean weight of 6 boys =48 kg.Let the weight of the 6th boy be a kg.650+45+50+42+40+a​=48=>227+a=288=>a=61weight of the 6th boy =61 kg.

Q360: If the cost of a loaf is Rs. 5.50. What is the cost of 2 1/2 loaves of bread?

Explanation

Let the triangle be $Δ A B C$
The sum of angles in triangle is $18 0^{\circ}$
$4 5^{\circ} + 6 0^{\circ} + ∠ C = 18 0^{\circ} ∠ C = 180 - 45 - 60 ∠ C = 7 5^{\circ}$

Mean weight of $6$ boys $= 48$ kg.
Let the weight of the $6$ th boy be a kg.
$\frac{5 0 + 4 5 + 5 0 + 4 2 + 4 0 + a}{6} = 48$
$= > 227 + a = 288 = > a = 61$
weight of the $6$ th boy $= 61$ kg.
