BODMAS QUESTIONS for class 5  with answers (Solved examples)

(i) 5 x 50 +57 -57 ÷ 57

Sol. 5 x 50 +57 -57 ÷ 57= 5 x 50 +57 -1                     (performing division first)

=250+57-1                             ( performing multiplication)

= 307-1                                    (performing addition )

= 306

(ii) 4+4+4+4 ÷ 4 

Sol. 4+4+4+4÷ 4  =4+4+4+1                                 (solving division)

= 13

(iii) 80+[20 x { 20-(10 ÷5) }] 

Sol.  80+[20 x { 20-(10 ÷5) }] = 80+[20 x { 20-2 }]                    (Solving the small brackets)

=80+[20 x 18]                              (removing braces)

=  80+360                                      ( performing multiplication)

=440

(iv)  10 x 10 +[400 ÷ {100-(50-\overline{3\times 10})}] 

Sol. 10 x 10 +[400 ÷ {100-(50-\overline{3\times 10})}] = 10 x 10 +[400 ÷ {100-(50-30)}]                 (removing bar)

= 10 x 10 +[400 ÷ {100-20}]                          (removing small brackets)

= 10 x 10 +[400 ÷ 80]                                        ( removing braces)

= 10 x 10 +5                       (removing big brackets and performing division)

= 100+5                               (performing multiplication)

=105

(v) [{64-(12+13)}÷3]+15

Sol.  [{64-(12+13)}÷3]+15 = [{64-25}÷3]+15                               (removing small brackets)

=[39÷3]+15                                           (removing braces)

= 13+15                                                 (performing division)

=28

(vi) 7614 +832  x 48  ÷ 16- 8 

Sol. 7614 +832  x 48  ÷ 16- 8 =7614 +832  x 3- 8         (performing division)

=7614 +2496- 8               ( performing multiplication)

= 10110-8

= 10102

(vii)  12- [20 ÷{8-2(9-5-2)}]  

Sol.   12- [20 ÷{8-2(9-5-2)}]  =12- [20 ÷{8-2 x 2}]                    (solving expression in small brackets)

=12- [20 ÷{8-4}]

=12- [20 ÷4]                                   (removing braces)

= 12  -5                                              (removing big brackets)

=7

(viii) 25-[16-{5+18÷(4-\overline{5-3})}]

Sol. (viii) 25-[16-{5+18÷(4-\overline{5-3})}]=25-[16-{5+18÷(4-2)}]                       (removing bar)

= 25-[16-{5+18÷2}]                            (removing small brackets)

= 25-[16-{5+9}]                                  (solving division inside curly braces)

=25-[16-14]

=25-2

=23

(ix) 15-[16-{12+21÷(9-2)}]

Sol. 15-[16-{12+21÷(9-2)}]=15-[16-{12+21÷7}]

=15-[16-{12+3}]

=15-[16-15]

=15-1

=14

(x) \mathbf{4\frac{1}{10}-[2\frac{1}{2}-\{\frac{5}{6}-(\frac{2}{5}+\frac{3}{10}-\frac{4}{15})\}]}

Sol. 4\frac{1}{10}-[2\frac{1}{2}-\{\frac{5}{6}-(\frac{2}{5}+\frac{3}{10}-\frac{4}{15})\}]=\frac{41}{10}-[2\frac{1}{2}-\{\frac{5}{6}-(\frac{2}{5}+\frac{3}{10}-\frac{4}{15})\}]

=\frac{41}{10}-[\frac{5}{2}-\{\frac{5}{6}-(\frac{12+9-8}{30})\}]

=\frac{41}{10}-[\frac{5}{2}-\{\frac{5}{6}-\frac{13}{30}\}]

=\frac{41}{10}-[\frac{5}{2}-\{\frac{25-13}{30}\}]

=\frac{41}{10}-[\frac{5}{2}-\frac{12}{30}]

=\frac{41}{10}-[\frac{75-12}{30}]

=\frac{41}{10}-\frac{63}{30}

=\frac{123-63}{30}=\frac{60}{30}=2
