A व B या दोन राशीतील संबंधाचे वर्णन करणारा उचित पर्याय निवडा. लाल्यू आणि जॉन हे रस्ता शर्यतीच्या स्पर्धेत धावत आहेत. लाल्यू 2 तासात 3/4 शर्यत पूर्ण करतो. लालूला 9/10 शर्यत पूर्ण करायला लागणाऱ्या वेळेच्या 5/8 वेळेत जॉन 2/3 शर्यत पूर्ण करतो. राशी A लाल्यूचा वेग राशी B जॉनचा वेग (1) दोन्ही राशी समान आहेत (2) राशी A लहान आहे (3) राशी B लहान आहे (4) राशीतील संबंध निश्चित करण्याच्या दृष्टीने माहिती पुरेशी नाही Select the appropriate option that describes the relation between quantities A and B. Lalu and John are competing in a road race. Lalu completes 3/4th of the race in 2 hours. John completes 2/3rd of the race in 5/8th of the time which Lalu takes to complete 9/10th of the race. Quantity A Lalu's Speed Quantity B John's Speed (1) Both the quantities are equal (2) Quantity A is smaller (3) Quantity B is smaller (4) Information is insufficient for determining the relation
Lalu's speed (Quantity A) = (3/4) / 2 = 3/8. For John, time taken by Lalu for 9/10th of race is (9/10) / (3/8) = 12/5 hours. John's time is 5/8 of this = 3/4 hours. John covers 2/3 of race in 3/4 hours, so John's speed = (2/3) / (3/4) = 8/9. Comparing 3/8 and 8/9, Quantity A is smaller.
