Q. In a row of girls, Nidhi and Heena occupy the ninth place from the ...
Given:
Nidhi is at ninth place from the right end.
Heena is at the tenth place from the left end.
After interchanging their places, Nidhi is at seventeenth place from the right end and Heena is at eighteenth place from the left end.

To find:
How many girls are there in the row?

Solution:
Let the number of girls in the row be N.
According to the given information, we can write the following equations:

N - 8 + 1 = 10 => N = 19 (Nidhi is at ninth place from the right end)
N - 10 + 1 = 17 => N = 26 (Nidhi is at seventeenth place from the right end)
N - 17 + 1 = 18 => N = 36 (Heena is at eighteenth place from the left end)

Therefore, the number of girls in the row is 26 (option B).

Explanation:
We can use the concept of the total number of people in a row to solve this problem. Here, we are given the positions of Nidhi and Heena from both ends of the row. By using these positions, we can write equations and solve for the total number of girls in the row.

Firstly, we are given that Nidhi is at the ninth place from the right end. So we can write:

N - 8 + 1 = 10, where N is the total number of girls in the row.
Here, we subtract 8 from N because Nidhi is at the ninth place from the right end. We add 1 because we want to count Nidhi as well. And we equate it to 10 because we are given that Nidhi is at the tenth place from the left end.

Simplifying this equation, we get N = 19.

Next, we are given that after interchanging their places, Nidhi is at the seventeenth place from the right end and Heena is at the eighteenth place from the left end. So we can write:

N - 16 + 1 = 17, for Nidhi's position from the right end.
N - 17 + 1 = 18, for Heena's position from the left end.

Simplifying these equations, we get N = 26 and N = 36, respectively.

Since we want the total number of girls in the row, we take the value of N from any one of the equations. Here, N = 26 satisfies all the given conditions. Therefore, the answer is 26.

Q. In a row of girls, Nidhi and Heena occupy the ninth place from the ...
So in this question they have given Nidhi and Heena place that is 9 & 10 so now they bhot have interchange their position with eachother that will become 17 & 18 so the solution will be
9+17-1= 26
so the option B is the correct ans of this question
Ans :- Their are 26 girls in a row

Similar CLAT Doubts

The appearance of sunspots has been considered to be roughly periodic, with an average cycle of eleven years. Moreover, the incidence of solar flares and the flux of solar cosmic rays, ultraviolet radiation, and x-radiation all vary directly with the sunspot cycle. But after more than a century of investigation, the relation of these and other phenomena, known collectively as the solar-activity cycle, to terrestrial weather and climate remains unclear.The absence of recorded sunspot activity in the notes kept by European observers in the late seventeenth and early eighteenth centuries has led some scholars to postulate a brief cessation of sunspot activity at that time (a period called the Maunder minimum). The Maunder minimum has been linked to a span of unusual cold in Europe extending from the sixteenth to the early nineteenth centuries. The reality of the Maunder minimum has yet to be established, however, especially since the records that Chinese naked-eye observers of solar activity made at that time appear to contradict it. Scientists have also sought evidence of long-term solar periodicities by examining indirect climatological data, such as fossil records of the thickness of ancient tree rings. These studies, however, failed to link unequivocally terrestrial climate and the solar-activity cycle, or even to confirm the cycle’s past existence.If consistent and reliable geological or archaeological evidence tracing the solar-activity cycle in the distant past could be found, it might also resolve an important issue in solar physics: how to model solar activity. Currently, there are two models of solar activity. The first supposes that the Sun’s internal motions interact with its large-scale magnetic field to produce a dynamo. The Sun’s large-scale magnetic field is taken to be self-sustaining, so that the solar-activity cycle it drives would be maintained with little overall change for perhaps billions of years. The alternative explanation supposes that the Sun’s large-scale magnetic field is a remnant of the field the Sun acquired when it formed, and is not sustained against decay. In this model, the solar mechanism dependent on the Sun’s magnetic field runs down more quickly. Thus, the characteristics of the solar-activity cycle could be expected to change over a long period of time. Modern solar observations span too short a time to reveal whether present cyclical solar activity is a long-lived feature of the Sun, or merely a transient phenomenon.Q. According to the passage, late seventeenth and early eighteenth-century Chinese records are important for which of the following reasons?
