Calendar of 2 years is similar if number of odd days between these two years is zero. Consider option one by one
(a) Between 1940 to 1946 we have two leap years 1940 and 1944 so number of odd days is 2 + 1 + 1 + 1 + 2 + 1 = 8 or 1 hence calendar of these two years is not similar.
(b) Between 1977 to 1982 we have one leap years 1980 so number of odd days is 1 + 1 + 1 + 1 + 2 + 1 = 6 calendar of these two years is not similar.
(c) Between 1912 to 1916 we have one leap years 1912 so number of odd days is 2 + 1 + 1 + 1 = 5 hence calendar of these two years is not similar.
Distance covered = 550 meter. = 0.55 km
Speed of the train = 55 km/hr
So time taken = 0.55 / 55 =1/100 hr = (60 x 60 )/100 sec = 36 sec
? = 953.7 ÷ 950.9989 = 95?
? 95(3.7 - 0.9989) = 95?
? 952.7011 = 95?
? ? = 2.7011 ? 2.7
❨ | √625 | x | 14 | x | 11 | ❩ | is equal to: |
11 | √25 | √196 |
Given Expression = | 25 | x | 14 | x | 11 | = 5. |
11 | 5 | 14 |
Time = | ❨ | 100 x 81 | ❩years | = 4 years. |
450 x 4.5 |
Therefore x = 21%
Total no.of boys : no. of girls = 13:27
27 : 13
Let the price of the mixed variety be Rs. x per kg. By the rule of alligation, we have :
Cost of 1 kg of type 1 rice Cost of 1 kg of type 2 rice
(20-x)/(x-15) = 2/3
60 - 3x = 2x - 30
x = 18.
pool : kerosene
3 : 2(initially)
2 : 3(after replacement)
(for petrol)
=> K = 30
Therefore the total quantity of the mixture in the container is 30 liters.
Let the capacity of the pot be 'P' litres.
Quantity of milk in the mixture before adding milk = 4/9 (P - 8)
After adding milk, quantity of milk in the mixture = 6/11 P.
6P/11 - 8 = 4/9(P - 8)
10P = 792 - 352 => P = 44.
The capacity of the pot is 44 liters.
