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-)}]
Sol. 10 x 10 +[400 ÷ {100-(50-)}] = 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-)}]
Sol. (viii) 25-[16-{5+18÷(4-)}]=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)
Sol.
