_______
Hence, the value of the given equation 55.55 + 155 + 15.55 + 0.5 + 0.05 = 226.65.
Correct Answer: 45
Explanation:
Let number of 20 ps coins = x and
number of 25 ps coins = y
Given total coins in the bag = 50
x + y = 50.......(1)
But the total money in the bag = Rs. 10.25
0.20x + 0.25y = 10.25
20x + 25y = 1025.........(2)
Now multiplying (1) by 25 we get
25x+25y=1250.............(3)
By solving (2) and (3)
20x + 25y = 1025;
=> x = 45;
Then, the no. of 20 ps coins are 45.
Correct Answer: 3
Explanation:
Given teacher drinks 9 ltr
Let number of boys be 'A'.
Let number of girls be 'B'.
Boy drinks 7 ltr and girl drinks 4 ltr
After class total water consumed = 42 ltr
Then,
9 + 7A + 4B = 42
=> 7A + 4B = 33
By trial and error method,
The only integers which satisfy the equation is A = 3 and B = 3
Therefore, number of girls in the class = 3.
Correct Answer: 9
Explanation:
26 trees have 25 gaps between them,
Required distance (225/25) = 9
Correct Answer: 1.75
Explanation:
56/32 can be reduced as
56/32
= 28/16
= 14/8
= 7/4
= 1 3/4
= 1.75
Hence, simplified value of 56/32 = 3/4 = 1.75.
Correct Answer: 0
Correct Answer: 95°F
Explanation:
Let F and C denotes the temparature in Fahrenheit anid Celcsius respectively.
Then, (F - 32) /(212 - 32) = (C - 0)/(100 - 0), if c = 35, then F = 95.
