Answers:
How does the ICC decide who umpires each series?
Let the amount of wheat consumption of the family be x quintals and let the constant expenditure be y rupees.So, formulating simultaneous equations based on the data given in the question:
250x + y = 1000 ---i)
240x + y = 980 ---ii)
Subtracting ii) from i), we get,
10x = 20
=> x = 2.
Putting x = 2 in equation i), we have
500 + y = 1000
=> y = 500.
Now, when the cost of wheat is Rs. 350,
we have the monthly expense as:
350 * 2 + 500 = 1200.
Thus, the montly expenditure is Rs. 1200.
what has this got to do with cricket.
is it the wheat thing, the fact that indians eat mainly wheat based foods and that cricket is the most popular sport in india.
