1 answer:
Answer
Find out the how many notes of each denomination did she give .
To prove
Let us assume that x be the scalar multiplication of the Rs 50, Rs100,Rs500 curreny notes.
As given
Kamala gave Rs 1,50,000 to her friend.
She gave currency notes of denomination Rs. 50,Rs.100,Rs.500 in the ratio 4:3:5.
Rs50 currency note gave in the denomination = 4x
Rs100 currency note gave in the denomination = 3x
Rs500 currency note gave in the denomination = 5x
than the equation becomes
4x + 3x + 5x = 150000
12x = 150000
x = 12500
Thus
Rs50 currency note gave in the denomination = 4 × 12500
= 50000
Rs100 currency note gave in the denomination = 3 × 12500
= 37500
Rs500 currency note gave in the denomination = 5 × 12500
= 62500

Answer:
Option A.
Step-by-step explanation:
From the first dot plot the given data set for week 1 is
62, 68, 68, 68, 69, 70, 70, 72, 72, 72, 75, 75, 76, 78, 78, 80, 80, 80, 89, 89
Divide the data in 4 equal parts.
(62, 68, 68, 68, 69), (70, 70, 72, 72, 72), (75, 75, 76, 78, 78), (80, 80, 80, 89, 89)
From the second dot plot the given data set for week 2 is
62, 68, 68, 68, 69, 70, 70, 72, 72, 72, 75, 75, 76, 78, 78, 80, 80, 80, 85, 86, 86, 86, 88, 88, 88, 88, 89, 89, 89, 89
Divide the data in 4 equal parts.
(62, 68, 68, 68, 69, 70, 70), 72, (72, 72, 75, 75, 76, 78, 78), (80, 80, 80, 85, 86, 86, 86), 88, (88, 88, 88, 89, 89, 89, 89)
The range for Week 1 is equal to the range for Week 2.
The median for Week 2 is more than the median for Week 1.
The mean for Week 2 is more than the mean for Week 1.
Therefore, the correct option is A.
