23.

certain number of notebooks were made from 10, 054 sheets of paper if one notebook requires 76 sheets how many notebooks were made how many sheets were left unused is ka solusion nikalo

Answer»

LET x number of notebooks were MADE

So 76 * x will give us the number of pages in the books

76x = 10054

x = 10054/76

x = 132 22/76 so we have here 132 whole and 22/76

When we DIVIDE 10054 by 76 we get quotient = 132

Remainder = 22

So we have still 22 SHEETS left unused

And 132 notebooks will be made with 22 sheets left unused

initially a shopkeeper had n chocolates. a customer bought 10% chocolate from n then another customer bought 20% of the remaining chocolates after that one more customer purchased 25% of the remaining chocolates. finally shopkeeper is left with 270 chocolates in his shop. how many chocolates were there initially in his shop?

Answer»

Initially = N CHOCOLATES

After CUSTOMER bought 10%

0.1 x n = 0.1n

n - 0.1n = 0.9n

After customer bought 25% of the remaining

0.25 x 0.9n = 0.225n

0.9n - 0.225n = 0.675n

There were 270 chocolates left

0.675n = 270

n = 270 ÷ 0.675

n = 400

Answer: There were initially 400 chocolates in his SHOP.

Answer» Let us number the balls from 1 to 8 Now make groups Ball group A = {1,2,3} Ball group B = {4,5,6} Ball group C = {7,8} Now WEIGH group A and B on weighing SCALE. If the lighter ball is in one of the two group you will know. Then suppose lighter ball is in group A, so take ball 1 and 2 and weight them, if any of them is lighter then it will weigh LESS on weighing scale but if not then you will know ball 3 is the lighter ball. If the lighter ball is in group B then weigh ball 4 and 5 if any of them is lighter then it will weigh less on weighing scale and if NONE of them is lighter then ball 6 is the light weight ball. But when in the start we weighed group A and B and suppose none have the lighter ball then we are SURE that lighter ball is in group C. Accordingly you can weigh ball 7 and 8 and you will get the lighter ball.

COST of 30kg at $10.5/kg = 30 x 10.5 = $315

Cost of 20KG at $11/kg = 20 x 11 = $220

Total cost = $315 + $220 = $535

Total kg = 30 + 20 = 50kg
