And 146*12=16431,then by their rule, 5346*xyz =086328.Then xyz =? a) 821 b) 128 c) 842 d) 248 3) A purchased 10 kg of rice and 12 kg of wheat whereas B purchased 10 kg of wheat and 12 kg of rice and both of them sell rice at 20% profit and wheat at 10% loss. After which A has a profit of Rs.10.40 and B has a profit of Rs.16. What is th4e price of 1kg of wheat and 1kg of rice? a) Rs.10, Rs.8 b) Rs.8, Rs.10 c) Rs.12, Rs.10 d) Rs.10, Rs.12 DIRECTIONS for questions (i) to (iv): Answer the questions based on the data given below. 4) There are seven cities A, B, C, D, E, F, and G connected to each other by a circular track. The following table shows the shortest possible distance between some cities along the circular track. There is no city in between F and D.
(i) What is the total length of the circular track? a) 110km b) 77km c) 88km d) 99km (ii) What is the shortest distance between B and F? a) 16 b) 24 c) 32 d) none of these (iii) If you can travel along just one diameter then what is the shortest possible distance between D and A? a) 32km b) 24 km c) 40 km d) 36 km (iv) City E lies between: a) A and F b) F and G c) A and G d) B and
