Answer:
the lcm of 15 and 18 is 90 and the gcf is 3
Step-by-step explanation:
multiple factors to get lcm and to get GCF Find the prime factorization of 15
15 = 3 × 5
Find the prime factorization of 18
18 = 2 × 3 × 3
To find the GCF, multiply all the prime factors common to both numbers:
Therefore, GCF = 3
Answer:
Amount = p( 1+r/100) ^n
= 12000 ( 1+10/100) ²
= 12000( 10/10+1/10) ²
= 12000( 11/10) ²
= 12000 x 11/10 x 11/10
= 14520 rs.
Compund interest = amount - principal
= 14520 - 12000
= 2520rs.
Next question :- no of men can complete a piece of work in 7 days = 36
No of men can complete a piece of work in 42 day = ( 36 x 7 ) ÷ 42
= 252 ÷ 42
= 6 men
The product is 28. 11-7= 4. 4×7=28
