To solve the equation:
18 1/6 ÷ 2 1/3
First, convert the mixed numbers to improper fractions:
18 1/6 = 109/6
2 1/3 = 7/3
Then, divide the fractions:
(109/6) ÷ (7/3) = (109/6) × (3/7) = 327/42
Simplify the fraction:
327/42 = 109/14
Convert the improper fraction back to a mixed number:
109/14 = 7 11/14
Simply remove (.) from 9.5 x 6 and multiply
95 x 6 = 570
Put (.) after one so answer 57
Explanation:
Let the C.P. of the article be Rs. x.
Then, required ratio = 104% of x / 106% of x= 104/106 = 52/53 = 52:53
15 × 1/4 = 15 ÷ 4 = 3.75
To find the answer, we can use the formula: (men1 * hours1) = (men2 * hours2)
(36 * 25) = (15 * x)
x = 60 hours
Total amount: 121
121 - 100 = 21.
*****
x + y = 67 ... (equation 1)
x - y = 3 ... (equation 2)
where x and y are the two numbers.
We can solve this system of equations by adding equation 1 and equation 2, which eliminates y:
2x = 70
Dividing both sides by 2 gives:
x = 35
Now that we have x, we can substitute it into equation 1 to find y:
35 + y = 67
Subtracting 35 from both sides gives:
y = 32
So, the two numbers are 35 and 32.
Selling price = Rs. 9 per Kg (at a loss of 20%)
Cost price = 9 / (1 - 0.20) = 9 / 0.80 = Rs. 11.25 per Kg
To make a profit of 5%:
Selling price = 11.25 x 1.05 = Rs. 11.81 per Kg
So, the correct answer is 11.81.
