Answer:
The cost of 1 note book = Rs 43.5
Step-by-step explanation:
Given in question as :
95 pens (P) + 89 notebook (N) total cost = Rs 7434
1 pen (P) + 1 (N) total cost = Rs 81
So, from above equation
95 pens (P) + 89 notebook (N) total cost = Rs 7434
1 × 95 pen (P) + 1× 95 notebook (N) total cost = Rs 81 × 95
Or, (95 pens (P) + 95 notebook (N) ) - (95 pens (P) + 89 notebook (N) ) = (7695 - 7434)
Or , 6 N = Rs 261
Or, N =
= Rs 43.5
Hence the cost of 1 notebook is Rs 43.5 Answer
The bin containing 382 red, yellow, blue and green balls have a total of 32 green balls.
Let x represent the number of red balls, y represent the number of yellow balls and z represent the number of green balls.
Since ther is a total of 382 balls, hence:
x + y + z = 382 (1)
There is three times as many red balls as yellow balls:
y = 3x
3x - y = 0 (2)
52 more blue balls than yellow balls, hence:
z = y + 52
- y - z = -52 (3)
Solving equations 1, 2 and 3 gives x = 62, y = 186, z = 134
Hence there are 62 red balls, 186 yellow balls and 134 blue balls
Green balls = 62 - 30 = 32 balls
