Your question is not complete it should be,
I: &600 fix and &50 per hourNow solving the question,Let the work is done in n hour as per given , So After n hour according to first scheme he will get an amount
= 600+50n After n hour according to second scheme he will get an amount,
=170nNow we are asked for values of n such that scheme
I give better wages so 600+50n >170n600>120nor n <5 .SO if the numbers of hour are less than 5 then he will get better wages by first scheme.

A plumber can be paid under two schemes as given below:I: Rs 600 and R...
Solution:

To find out the values of n for which scheme I will give the plumber better wages, we need to compare the wages earned under both schemes for the given time period.

Under the first scheme, the total wages earned by the plumber will be:

Wages = Fixed amount + Hourly rate x Number of hours

Wages = 600 + 50n

Under the second scheme, the total wages earned by the plumber will be:

Wages = Hourly rate x Number of hours

Wages = 170n

Now, we need to find out the values of n for which Wages(I) > Wages(II). Substituting the above values of wages in the inequality, we get:

600 + 50n > 170n

Solving for n, we get:

n < />

Therefore, the plumber will earn more under Scheme I for n < 12="" hours.="" but="" since="" we="" are="" asked="" to="" find="" the="" values="" of="" n="" for="" which="" scheme="" i="" will="" give="" better="" wages,="" we="" need="" to="" check="" which="" of="" the="" given="" options="" satisfy="" this="" />

a) For n < 4="" hours,="" wages(i)="600" +="" 50n="" />< />

Wages(II) = 170n

Therefore, Wages(II) > Wages(I) for n < 4="" />

b) For n < 5="" hours,="" wages(i)="600" +="" 50n="" />< />

Wages(II) = 170n

Therefore, Wages(II) > Wages(I) for n < 5="" />

c) For n > 5 hours, Wages(I) = 600 + 50n > 850

Wages(II) = 170n

Therefore, Wages(I) > Wages(II) for n > 5 hours.

d) For n = 4 hours, Wages(I) = 800

Wages(II) = 680

Therefore, Wages(I) > Wages(II) for n = 4 hours.

Hence, the correct answer is option (b) i.e., less than 5 hours.

Directions:Read the following passage carefully and choose the best answer to the given question out of the four alternatives.Crop insurance in India accounts for less than 2% of income generated from agriculture in a year. This, despite the fact that more than 60% of India’s labour force is dependent on agriculture, and the remaining two sectors — industry and services — derive a large part of their demand from agriculture. Further, Indian agriculture is still subject to uncontrollable risks, prime among which are the vagaries of the monsoon. A large part of crop insurance happens in the kharif season, which is critically monsoon-dependent. About 82% of total sum insured is for the kharif crop as are the 87% of the farmers who have so far benefited from crop insurance schemes. Nevertheless, in absolute terms, crop insurance’s role in agriculture is miniscule compared to agriculture’s significance to the country. The total insured crop area is only about 10% of the overall area under food grains.This suggests that not too much headway has been made in agriculture insurance since its initiation. The first nationwide crop insurance scheme, Comprehensive Crop Insurance Scheme (CCIS), which was launched in 1985-86 by the General Insurance Corporation (GIC), did not achieve much. Over the years of its operation, the CCIS insured a total of 1.1% of the agriculture GDP over the period. From 1999-2000, a new scheme — the National Agriculture Insurance Scheme (NAIS) — was launched in place of the CCIS, with a newly-formed Agriculture Insurance Company of India (AIC) as its implementing agency. This has fared slightly better than the CCIS, partly because of its scope. While the CCIS insured only those farmers who had taken short-term loans, the NAIS covers all farmers. The average yearly sum insured forms about 3% of income generated by agriculture in a year. Some of the bigger crop-producing states like Punjab, Haryana and Rajasthan did not participate in the insurance scheme. These account for 19% of the total food grain area in the country. Presumably, the area as well as sum insured would have been far larger if these states had participated as well.All the other major food crop-producing states are part of the NAIS. They account for 74% of the overall food grain area. NAIS data suggests that almost all the claims made so far have also been in the kharif season, with rabi season claims accounting for less than 1% of the total claims. This is understandable given that India has had at least two major droughts since the initiation of NAIS. However, a proportionately lower premium is paid during the kharif season, which accounts for 86% of total premiums while claims from this season are 99% of total claims.Q.Around 90% of the overall area under food grains
