loop bus has exactly six stops on its route. The bus first stops at stop one and then at stops two, three, four, five and six in that order. After leaving stop six, the bus returns to stop one and continues around the loop again. The stops are at six buildings that are, in alphabetical order, Gendaria, Hatirpool, Jigatala, Khilgaon, Lichubagan, and Mohammadpur. • Lichubagan is stop three. • Hatirpool is stop six. • Khilgaon is the stop immediately before Mohammadpur. • Jigatala is the stop immediately before Gendaria. If Jigatala is stop four, which of the following must be the stop immediately before Lichubagan?
Explanation: ধরে নিই, Gendaria G, Hatirpool H, Jigatala J, Khilgaon K, Lichubagan = L আর Mohammadpur = M। J যেহেতু stop 4 এ আছে, stop 5 এ থাকবে G (Jigatala is immediately before Gendaria)। Stop 3 হল L. Khilgaon is immediately before Mohammadpur. Stop 6 হল H. 6 stops in order: \(\text{S}1, \text{S}2, \text{S}3(L), \text{S}4(J), \text{S}5(G), \text{S}6(H)\). If J is S4, then G must be S5. L is S3. Stops 1, 2 must be K and M. K is before M. So S1=K, S2=M. The order is K, M, L, J, G, H. The stop immediately before Lichubagan (L) is Mohammadpur (M).
