Ques:- In 3.5 Kg rod , there is 74% silver. If it is alloyed with a 0.5 Kg rod, the % of silver goes p to 84%. The percent of silver in 0.5 Kg rod?
Recent Answer : Added by Munesh On 2022-08-14 16:29:31:

In 3500 g rod contains 74% of silver = 3500 * 74/100 = 2590 g
Then 3500 g + 500 g of rod contains 84% of silver
Let x be the silver contained in 500 g of silver
(2590/3500 * 100) + (x/500 * 100) = 84
74 + x/5 = 84
(370 + x) /5 = 84
370 + x = 420
x = 50
Then the percentage of silver contained in 500 g of rod = 50/500 *100 =10%

90 inches

Slab = 6(x) where x is each step
Slab = 5(x + 3)

6(x) = 5(x + 3)
6(x) = 5(x) + 15
x = 15 inches

So 6(x) = 6(15) = 90

Check: 5( x + 3) = 5(18) = 90

Slab size is 90 inches
