(A) 14 (B) 28 (C) 49 (D) 144 (E) 196 The area of square whose has length of 2 jin in each side is = 2j * 2j = 2*14 d * 2*14 d The area of square whose has length of 2 ducks in each side is = 2d * 2d Hence to tal square required : \(\frac{(2*14 d * 2*14 d)}{(2d * 2d)}\) = \(14*14 =196\) Hence Ans E

(A) 14 (B) 28 (C) 49 (D) 144 (E) 196 No of squares=Area of the square with side length of 2 jins/Area of the square with side length of 2 daksArea of the square with side length of 2 jins(=2*14 daks=28 daks)=28*28 square daks Area of the square with side length of 2 daks=2*2=4 square daks So , no of squares=\(\frac{28*28}{4}\)=196 Ans. (E)

as 1 jin = 14 daks so, 2 jin = 28 daks area of square with 28 dak length \(= 28^2 = 784\) area of square with 2 dak length = 4 total number od squares in large square \(= \frac{784}{4} = 196\)

Your explanation, and by extension your approach, is straight forward. In my opinion this was a <35 second question, for which one ought to have a crystal clear picture of the required equations in mind. hasnain3047 wrote: as 1 jin = 14 daks so, 2 jin = 28 daks area of square with 28 dak length \(= 28^2 = 784\) area of square with 2 dak length = 4 total number od squares in large square \(= \frac{784}{4} = 196\)

(A) 14 (B) 28 (C) 49 (D) 144 (E) 196 1 jin = 14 daks hence 2 jin = 28 daks Number of squares = Area of 28 square daks/ Area of 2 square daks = 28*28/2*2 =196 Hence Option E solved in 30 seconds

Solution Given:• dak is a unit of length and 14 daks = 1 jin
To find:• The number of squares with a side length of 2 daks can fit in a square with a side length of 2 jins Approach and Working: • 2 Jins= 28 daks. • Hence, area of the square of the side length 2 jins= pi * \((28)^2\)
o And, area of the square of the side length 2 daks= pi *\((2)^2\)= 4 pi Let us assume that ‘n’ squares of side length 2 daks can fit in a square of side length 2 jins. • Hence, n* 4 pi= pi* \((28)^2\)
Hence, the correct answer is option E. Answer: E
