If he sells $5264 worth of goods in a particular month, find his total income for that month. 2>Of the candidates from a certain school who sat for the Maths exam at 'A' level, 18%obtained grade A, 38% obtained grade B, the rest obtained grade C. Find the total no. of candidates given that 77 candidates obtained grade C.

最佳解答:

1. His total income of that month =$(520+5264x25%) =$1836 2.Let y be the total number of candidates obtained grade C. y(100%-18%-38%)=77 y(44%)=77 y=175 Therefore, the total no. of candidates obtained grade C is 175.

其他解答:

1. 520 + 5264x25% = $1836 2. percentage for grade "c" candidates = 100-18-38 = 44% total no. of candidates = 77/44% = 175nos.|||||1> His total income = basic salary + commission = $520 + $5264x25% = $1836 2> % of candidates obtained grade C = 100%-18%-38% = 44% Total no. of candidates = 77/44% = 175 candidates|||||1>A door -to-door salesman is paid a basic salary of $520 per month plus a commission of 25% of total sales made during the month. If he sells $5264 worth of goods in a particular month, find his total income for that month. His total income of that month = Basic salary + Commission = $520 + $5264 x 25% ... ($5264 x 25% = commission of 25% of total sales) 2>Of the candidates from a certain school who sat for the Maths exam at 'A' level, 18%obtained grade A, 38% obtained grade B, the rest obtained grade C. Find the total no. of candidates given that 77 candidates obtained grade C. The total percentage of candidates obtained grade C = 1 - 18% - 38% = 44% The total no. of candidates = 77 ÷ 44%
