1 Given (a) RM20,000 for 5 years at 12% a year (b) RM10,000 for 3 years 8 months at 9% a year (C) RM15,000 for 3 – years at 11% a year 4 (d) RM7,000 for 40 weeks at 5% a year (e) RM8,000 for 20 months at 4% a year Find (i) simple interest earned, (ii) simple amount

Answer 1

Solution (a) Principle Amount = P = RM 20,000 Time = 5 years Rate of interst =R=12% (i) Simple Interest (I ) = PxNXR 100. year = 20,000 X SX12 10o =12000 = P + 1. (i) Simple Amount = 20,000+ 12000 = 32000 - RM 12000 Simple interest earned amount = RM 32000 simple (b) Principle Amount = P RM 10,000 8 months N 3 years lime = 3 + 8 12. Dyrs I year = 12 months I moth үн 3+ 3 yos. = 9+2 a year. = 1/3 yos Rate of interest = R=9%.. is Simple 'Interest (1) 10000 x 4Xg 100 = Px NXR 100

= 10,000 Xlx 3 100 = 33 00 (ii) Simple Amount P+1. = 10000 + 3300 = 13300. Simple Interst Simple Amount = RM 3300. RM 13300 (0) Principle Amount =P =RM 15000 Time EN = 34 years. = 13 years. 4 4 Rate of interest =R = 11% a year w Simple Interst(I)PXNXR loo = 15000x la Too IS000x13x1| 400 536205 (ii) Simple Amount = P + I, = 15000 +536205 =20362.5 RM Simple Interset 5362.5 = Amount RM 50362.5 Simple =

(d) Principle Amount =p = RM 7000 Slime =N 40 weeks Hyr=52 weeks 1 week = }zyo yus. 13 Rate of interst = 5% a year ci Simple Interest (1) = PxNxR Too Fooo X10 X5 3 100 = 7000x10x5 1300 269.2307 = 269.23 (10) Simple Amount = P+I. = 7000 + 269.23 = 7269.23 Simple Interst Simpre Amount RM 269.23 = RM 7269.23

les Principle Amount = P = RM 8000 . time =N= 20 months 20 years. ş years Rate of interst = 4% lyr = 12 months 1 month - L to yo a year (i) simple Interest (I) =PXNXR oܘܐ = 8000* Şx 4 Too = 8000x5X4 300 533.33 (i) Simple Amount = P + I. = 8000 + 5 33.33 = 8533.33 Simple Interest = RM 533.33 Simple Amount = RM 8533-33
