Answer 2

Answer:

Step-by-step explanation:

2.if the number of bulbs is 1560 then the answer will be

$\frac{15}{100}$×1560=234

if it is 560 calculate in the same way mentioned above instead of 1560 put 560 and your final answer will be 84

3.$\frac{60}{100}$×150=90

4.$\frac{80}{100}$×7200=5760

amount he saves= monthly income -- household expenses

                            = 7200-- 5760

                            =1440

5.$\frac{15}{100}$×2500=375

manju contributed 375 rupees

6.$\frac{30}{100}$×30=9

since the weight of suitcase is less than bag

weight of suitcase=weight of bag -- 30% weight of bag

                              = 30--9

                              =21 kg
