Mathematics Exercises

One such pair could be: (a)–10, 3(b)– 6, 4; (– 6 – 4 = –10)(c)–3, 3

One such pair could be: (a)–2, –10; [–2 – (–10) = 8](b)– 6, 1 (c)–1, 2; (–1 – 2 = –3)

Scores of both the teams are same, i.e., –30; Yes

(i)–5(ii)0(iii)–17(iv)–7 (v)–3

(a)–3(b)–225(c)630(d)316(e)0 (f)1320(g)162(h)–360(i)–24(j)36

One way of doing this is:

(i)(d)(ii)(b)(iii)(a)(iv)(c)

(i)(c)(ii)(a)(iii)(b)

Mode = 20, Median = 20, Yes.

Mean = 39, Mode = 15, Median = 15, No.
