Madhre is standing in the middle of a bridge which is 20 m above the water level of a river. If a 35 m deep river is flowing under the bridge (see Fig. 1.1), then the vertical distance between the foot of Madhre and bottom level of the river is:
55 m
35 m
20 m
15 m

Find the odd one out of the four options in the following:
(–2, 24)
(–3, 10)
(–4, 12)
(–6, 8)
All the pairs i.e. (–2, 24); (–4, 12); (–6, 8) give same answer on multiplication, whereas –3 × 10 = –30, gives a different answer. So, odd one is (–3, 10)
Find the odd one out of the four options given below:
(–3, –6)
(+1, –10)
(–2, –7)
(–4, –9)
All of these pairs i.e. (–3, –6); (+1, –10); (–2, –7) give same answer on adding, whereas – 4 + (–9) = –13, gives a different answer. So, odd one out is (–4, –9).
