Find the least number which when divided by 28, 50 and 140 leaves a remainder 7 ​

21

Step-by-step explanation:

First we have to find LCM (lowest common multiple) of the given number, i.e 700.

LCM = 2 × 2 × 5 × 5 × 7 = 700

now, let's add 7 to 700

We get the required number as 707

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
