Exercise- 4F
Que-1: Find :
(i) 1/8 of 40 (ii) 4/11 of 4*(2/5) (iii) 1*(3/5) of 6*(1/4)
(iv) 3/4 of Rs1 (v) 5/8 of 1 km (vi) 5/12 of 1 hour
Solution- (i) 1/8 x 40
= 5 Ans.
(ii) 4/11 x 22/5
= 8/5 = 1*(3/5) Ans.
(iii) 8/5 x 25/4
= 10 Ans.
(iv) 3/4 x 1
= 0.75 = 75 paisa
(v) 5/8 x 1
= 0.625 = 625 Ans.
(vi) 5/12 x 1
= 0.25 = 25 minutes Ans.
Simplify :
Que-2: 1*(1/6) ÷ 1*(5/9) x 3*(1/3)
Solution- 7/6 ÷ 14/9 x 10/3
= 7/6 x 9/14 x 10/3
= 5/2 = 2*(1/2) Ans.
Que-3: 1*(1/3) ÷ 3/7 of 2*(5/8) + 1*(1/9)
Solution- 4/3 ÷ 3/7 x 21/8 + 10/9
= [4/3 x 8/9] + 10/9
= 32/27 + 10/9
= (32 + 30)/27
= 62/27 = 2*(8/27) Ans.
Que-4: 6*(1/5) ÷ 3*(1/10) of 2*(1/2) ÷ 1/4
Solution- 31/5 ÷ 31/10 x 5/2 ÷ 1/4
= 31/5 ÷ 31/4 ÷ 1/4
= 31/5 x 4/31 x 4
= 16/5 = 3*(1/5) Ans.
Que-5: 3*(2/3) – 3/11 of 2*(3/4) ÷ 1*(1/4) x 1*(2/3) + 1/3
Solution- 11/3 – 3/11 x 11/4 ÷ 5/4 x 5/3 + 1/3
= 11/3 – 3/4 x 4/5 x 5/3 + 1/3
= 11/3 – 1/1 + 1/3
= (11 – 3 + 1)/3
= 9/3 = 3 Ans.
Que-6: 2*(2/7) of 15*(3/4) x 2*(1/4) ÷ 4/7 of 2*(5/8)
Solution- 16/7 x 63/4 x 9/4 ÷ 4/7 x 21/8
= 36 x 9/4 ÷ 3/2
= 36 x 9/4 x 2/3
= 27 x 2 = 54 Ans
Que-7: 1 ÷ 4/7 – 1/3 of 3*(3/4) + 1/2 ÷ 3
Solution- 1 ÷ 4/7 – 1/3 x 15/4 + 1/2 ÷ 3
= 1 x 7/4 – 5/4 + 1/2 x 1/3
= 1 x 7/4 – 5/4 + 1/6
= 7/4 – 5/4 + 1/6
= (21 – 15 + 2)/12
= 8/12 = 2/3
Que-8: [2/3 + 4/9] of 3/5 ÷ 1*(2/3) x 1*(1/4) – 1/3
Solution- [(6 + 4)/9] of 3/5 ÷ 5/3 x 5/4 – 1/3
= 10/9 x 3/5 x 3/5 x 5/4 – 1/3
= 2/3 x 3/4 – 1/3
= 2/4 – 1/3
= (6 – 4)/12
= 2/12 = 1/6 Ans.
Que-9: [14/15 ÷ 1*(1/6) + 7/10] x 3/4
Solution- [14/15 ÷ 7/6 + 7/10] x 3/4
= [14/15 x 6/7 + 7/10] x 3/4
= [4/5 + 7/10] x 3/4
= [(8 + 7)/10] x 3/4
= 15/10 x 3/4
= 9/8 = 1*(1/8) Ans.
Que-10: 1/3[2*(1/2) + 3*(1/3)] ÷ 2/9[3*(1/8) – 1*(1/12)]
Solution- 1/3 [5/2 + 10/3] ÷ 2/9 [25/8 – 13/12]
= 1/3 [(15 + 20)/6] ÷ 2/9 [(75 – 26)/24]
= 1/3 x 35/6 x 9/2 x 49/24
=
Que-11: [1/4 – 1/9] ÷ [1/2 + 1/4 ÷ 1/3]
Solution- [1/4 – 1/9] ÷ [1/2 + 1/4 ÷ 1/3]
= [(9 – 4)/36] ÷ [1/2 + 1/4 x 3]
= 5/36 ÷ [1/2 + 3/4]
= 5/36 ÷ [(2 + 3)/4]
= 5/36 ÷ 5/4
= 5/36 x 4/5
= 1/9 Ans.
Que-12: 3*(7/8) – {1*(3/8) ÷ [2*(4/5) – 1*(7/10)]}
Solution- 31/8 – {11/8 ÷[14/5 – 17/10]}
= 31/8 – {11/8 ÷[(28 + 17)/10]}
= 31/8 – {11/8 ÷45/10}
= 31/8 – {11/8 x 10/45}
= 31/8 – 22/72
= ( – 22)/40
= 133/40 Ans.
Que-13: 3÷[3 x {3 – (3 – 1/4)}]
Solution– 3÷[3×{3-(3-1\4)}]
= 3÷[3×{3-(3\1-1\4)}]
=3÷[3×{3-(11\4)}]
=3÷[3×{3\1-11\4}]
=3÷[3×{1\4}]
=3÷3\4
=3×4\3
=4 Ans.
Que-14- 5*1/3-[2*(1/3) ÷ {3/4 – 1/2 x (7/10 – 3/5)}]
Solution- 5*1\3-[2*1/3÷{3/4-1/2×(7/10-3/50)}]
=16/3[7/3÷{3/4-1/2×(7-6/10)}]
=16/3-[7/3÷{3/4-1/2×(1/10)}]
=16/3-[7/3÷{3/4-1/2×1/10}]
=16/3-[7/3÷{3/4-1/20}]
=16/3-[7/3÷{15-1/20}]
=16/3-[7/3÷{14/20}]
=16/3-[7/3÷{7/10}]
=16/3-[7/3÷7/10]
=16/3-[7/3×10/7]
=16/3-[10/3]
=16/3-10/3
=6/3
=2 Ans.
