Answer 2

Answer:

(4)4.4 METRE

(5)77

(6)0

Step-by-step explanation:

(4) LENGTH OF THE ELASTIC BAND=4 METRE

     INCREASED BY 10%

                          SO,

10/100*4= 1/10*4= 4/10= 2/5= 0.4

SO THE LENGTH OF THE ELASTIC BAND WAS INCREASED BY- 0.4

                           =4+0.4= 4.4 METRE

(5) FIRST, SECOND AND THIRD TERMS= 21,49 AND 33

   LET THE FOURTH PROPORTION BE X      

      SO IN PROPORTION WE SAY= 21:49::33:X

           X=49*33/21

              =1617/21

             =77

(6) 5-8/4 OF 2-1

         5-8/4*2-1

         5-2*2-1

          5-4-1

           1-1

           =0
