The cost of 10 balls is rupees 36 , Find the cost of 48 balls using ( the method ) 1. unitary method
2. Direct variation method

only answer if you know the answer
the sum must be done in both methods

Answer :-

Step by step explanation :-

Cost of 10 balls = 36

Cost of one ball = 36 / 10 => 3.6

Cost of 48 balls = 48 × 3.6

=> 172.80

No. of balls (a)

10

48

Cost of balls ( b)

36

y

Direct Variation ( a / b )

Cost of 48 balls is 172.80 rupees

50- 250 is correct i did that one too

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
