Answer:
et the number of Rs 5 coins be x.
Number of Rs 2 coins = 3 × Number of Rs 5 coins = 3x
Number of Re 1 coins = 160 - (Number of coins of Rs 5 and of Rs 2)
= 160 - (3x + x) = 160 - 4x
Amount of Re 1 coins = Rs [1 × (160 - 4x)] = Rs (160 - 4x)
Amount of Rs 2 coins = Rs (2 × 3x)= Rs 6x
Amount of Rs 5 coins = Rs (5 × x) = Rs 5x
It is given that the total amount is Rs 300.
∴ 160 - 4x + 6x + 5x = 300
160 + 7x = 300
On transposing 160 to R.H.S, we obtain
7x = 300 - 160
7x = 140
On dividing both sides by 7, we obtain
x = 20
Number of Re 1 coins = 160 - 4x = 160 - 4 × 20 = 160 - 80 = 80
Number of Rs 2 coins = 3x = 3 × 20 = 60
Number of Rs 5 coins = x = 20
Q16 :
The organizers of an essay competition decide that a winner in the competition gets a prize of Rs 100 and a participant who does not win gets a prize of Rs 25. The total prize money distributed is Rs 3000. Find the number of winners, if the total number of participants is 63.
Answer :
Let the number of winners be x. Therefore, the number of participants who did not win will be 63 - x.
Amount given to the winners = Rs (100 × x) = Rs 100x
Amount given to the participants who did not win = Rs [25(63 - x)]
= Rs (1575 - 25x)
According to the given question,
100x + 1575 - 25x = 3000
On transposing 1575 to R.H.S, we obtain
75x = 3000 - 1575
75x = 1425
On dividing both sides by 75, we obtain
x = 19
Hence, number of winners = 19

Answer:
GOLGI APPARATUS :-
The Golgi apparatus, first described by Camillo Golgi.
Golgi Apparatus is the cell organelle which helps in the formation of lysosomes.
This cell organelle also helps in packaging.
Golgi bodies consist of a system of membrane - bound vesicles arranged in stacks parallel to each other called cristerns.
These membranes have connections with the membrane of endoplasmic reticulum.
FUNCTIONS :-
The material synthesised near the Endoplasmic Reticulum is packaged and dispatched to various target inside and outside the cell through Golgi apparatus.
It also stores, modifies and helps in the packaging of products in vesicles.
In some case, complex sugars may be made from simple sugars in it.
It also helps in the formation of lysosomes.
