The weights in grams of 50 apples picked at random from a consignment are as follows 106, 107, 76, 82, 109, 107, 115, 93, 187, 195, 123, 125, 111, 92, 86, 70, 126, 68, 130 129, 139 119, 115, 128, 100, 186, 84, 99, 118, 204, 111, 141, 136 123, 90, 11 98, 110, 78, 90, 107, 81, 131, 75, 84, 104, 110, 80, 118, 82. Form the grouped frequency table by dividing the variable range into intervals of equal width, each corresponding to 70 gms in such a way that mid-value of the first class corresponds to 70 gms.

Find the mean of data 130, 90, 25, 77, 250, 100 (A) 25 (B) 77 (C ) 112 (D) 120

Find x if x/5-x/6=4 . (a)-120 (b) -100 (c) 100 (d) 120

If x=100, then 120% of x is 125 (b) 115120 (d) 110

If 1/5-1/6=4/x , then x= -120\ (b) -100 (c) 100 (d) 120

Assertion : The range of the data 114, 115, 116, 118, 119, 125, 130, 141, 126, 116, 113, 118, 120, and 126, is 100 Reason : The difference between the highest and the lowest value of the data is called range

Add : 5.412.84 and 115.2
