दिलेल्या माहितीच्या संदर्भात उचित पर्याय निवडा. A, B व C या बागा एका सपाटीवर आहेत पण एका रेषेत नाहीत. A व B या बागांतील अंतर 40 किमी आहे आणि A व C या बागांतील अंतर 110 किमी आहे. राशी X = B व C या बागांतील अंतर राशी Y = 60 किमी (1) X ही राशी मोठी आहे. (2) Y ही राशी मोठी आहे. (3) दोन्ही राशी समान आहे. (4) दिलेल्या माहितीच्या आधारे राशीतील सहसंबंध निश्चित करता येणार नाही. Select the appropriate option with respect to the given information. Parks A, B and C lie in a plane but do not lie on a straight line. The distance between Parks A and B is 40 km, and the distance between Parks A and C is 110 km. Quantity X = Distance between Parks B and C Quantity Y = 60 km (1) Quantity X is greater. (2) Quantity Y is greater. (3) The two quantities are equal. (4) The relationship cannot be determined from the information given.

a)Quantity X is greater.✓ Correct
b)Quantity Y is greater.
c)The two quantities are equal.
d)The relationship cannot be determined from the information given.

According to the triangle inequality theorem, the third side of a triangle must be greater than the absolute difference of the other two sides and less than their sum. Here, |110 - 40| = 70 < X < 110 + 40 = 150. Since X can be anything between 70 and 150, X could be greater than 60, but we cannot uniquely determine a single value for X compared to Y = 60 without more data, wait - actually triangle inequality says X > 70, so X must be greater than Y (60). Thus Quantity X is greater.
